Let me explain Sai and Ino's love life to everyone who is still saying "I don't know how they ended up together": 💜
People really be jumping to Boruto series without knowing what has happened in the Naruto series after the war arc. So here is Sai and Ino's relationship throughout the entire Naruto canon timeline.
First and foremost, Sai and Ino met in the very early episodes of Naruto Shippuden. Ino immediately had a crush on him because he was handsome, also noting that he looked like Sasuke. That is basically Ino, the flirty girl as we know. Having a crush and falling in love are two very different things.
Sai was introduced as a character with no emotions and feelings whatsoever. The reason why he thought Ino is "ugly" in their first interaction was because he didn't know what a real beauty is. He had no emotions/feelings, how do u expect him to understand beauty? Ironically, despite this, he called the opposite of what he thought at her, "Mrs. Beautiful" - building the foundation of SaiIno (Also Ino being the only person who didnt get insulted by Sai's nicknames.)
So, here Sai thought Ino was ugly and Ino had a crush on Sai solely because he was handsome. Two flaws, alright. Most of the fans know their relationship up to here. But that's not even close to the end of Sai and Ino's relationship before their marriage.
Moving on. As Sai and Ino are both side characters, they had almost no interactions on-screen afterwards in the manga, until the Fourth Shinobi War Arc. In the war, both Ino and Sai had each other in their Infinite Tsukyomi dreams. Ino dreamed of Sasuke and Sai fighting over her and Sai dreamed of Ino, along with his other close friends acknowledging his smile. (Sai's dream was in anime-only).
This proves that both have had interactions off-screen to the point that they were already very close friends before the war began. Morever, their Inifinte Tsukuyomi dreams reveal that by the war arc, Ino likes Sai as much as Sasuke (as she did not choose Sasuke over Sai in her ideal life/dream), and Sai likes Ino complimenting him.
During the long timeskip after the war Ino and Sai eventually starts dating. This was revealed in a spin-off manga chapter written in Akamaru's point of view by Kishimoto, where he spotted Sai and Ino together on a date and described them as "A couple totally on fire".
Around a decade later, in the very last chapter of the Naruto Shippuden manga (Chapter 700), they were shown married with a son together.
That's the end of Naruto manga contents for Sai and Ino's relationship, as expected not much because Naruto manga is NOT a romance manga.
Now, for those who wanted to know more about Sai and Ino's romance and the ship's further build up during the timeskip between the end of war and Boruto (Blank Period), there was a Novel series called Hiden. (Note: All Blank Period Hiden Novels are approved canon, illustrated and proof-read by Masashi Kishimoto, the author of the Manga himself). The Blank period is a part of the official canon timeline.
As mentioned above Novels are the stories of all the important events that took place during this blank period, including the romance between the characters. Get ready to hear one of the cutest love stories of Naruto series.
Ino lost her crush on Sasuke long back and is pretty much not into any relationship. This was until in Shikamaru Hiden events, Ino read a letter which describes Sai's tragic life. Since then Ino wanted to know even more about him than she already does. Ino was sent on a mission with her fellow ninjas to help Shikamaru and save Sai, who has been caught in a very strong enslaving genjutsu by some enemies. Her top priority after reading the letter was nothing but to save Sai.
As they confronted the genjutsu-controlled Sai, for some reason Ino believed that she is the only person who could save Sai. Ino risked her life and used her Mind Transfer Jutsu on Sai, in other words, Ino's soul entered Sai's body. Ino dived deep into his mind but all she could see was darkness. She didn't give up and tried to find his soul by diving even deeper into his mind despite the fact that it could be a threat to her own soul too. Ino finally found Sai's soul crying deep inside, covered with his memories and darkness. Ino learnt about him (in the novel it says "She knew all about him so much that it hurt her"). Ino called out for him and showed his soul the path out of the darkness. Ino cleared his mind hence saving him from the genjutsu, also giving colors to his colorless soul. Ino's soul then hugged Sai's soul with a heartfelt smile ~ A hug between two souls.
This is the point where both of them fell deeply in love. The point Sai achieved his dream, the point where he got his emotions and feelings completely back. This is the first time he felt this much kindness from someone and learned what a true beauty is. When Sai is successfully saved by her, the two wake from Ino's jutsu and Sai finds himself resting on Ino's laps. Sai instinctively reaches for Ino's hands and he expresses his gratefulness to her, as her eyes begin to tear up, by affectionately calling her "Thankyou, Miss Beautiful". This time, he truly meaning this unlike the first time he called her beautiful. "Idiot" - replied Ino. And this time, Ino fell in love with Sai, not because he resembles Sasuke unlike the first time they met. This interaction was the complete opposite of the first time they met. This is how their love story began ladies and gentlemen. *Tears because how beautiful this is*
Later, while Ino and Sakura was on their way to Sand village to participate in an international Medical Ninja Conference, Ino reveals her love for Sai to Sakura after what happened. She was thinking of confessing her love to him properly but was unsure which flower to give him: Flower Dogwood or Lavender. Ino, the botanist explains that in Flower language, Dogwood means "Accept my feelings" while Lavender means "I'm waiting". Sakura tells that Ino was more of Flower Dogwood type, as she wants a direct answer from Sai. Whilst for Sakura herself, Lavender will be the best because she is willing to wait for Sasuke.
When they returned back to Konoha after the conference, Ino finds out Kakashi has sent Sai alone on a dangerous mission. Ino gets worried and questions his safety, and is angry that Kakashi let him go alone. After Sai returned and Sakura got kidnapped, Ino ran to Sai's place to inform him about Sakura's disappearance. When she arrives, she becomes flustered to see Sai only in his underwear, as he was taking a shower right before she came.
Following the crisis, Sai and Ino together goes on a mission alone to save Sakura upon Hokage's orders. They are the only couple besides Sakura and Sasuke who did a mission together alone in canon. Sai and Ino flew on a Choju Giga Bird, and Sai comforted Ino as she was afraid flying and had a difficulty maintaining the balance, causing her to feel a sweet warm sensation well up within her heart. They both together infiltrated a hideout. The Saiino duo's teamwork was amazing and flawless.
After Sakura is saved, they had to fight the enemies. Ino, who has been usually positioned near the back lines during close ranged combat situations was now instead supporting Sai with her taijutsu and healing Sai's injuries with her medical ninjutsu. Sai and Ino confronted a very powerful enemy, Magire who was drugged with Tailed Beast chakra, but their flawless teamwork and bond strength lead to their victory. Sakura, and Sai himself compliments Ino on how well she works together as a duo with Sai, getting Ino blush even more. Later Sakura prompted Ino and Sai to have a date dinner together, where Ino possibly confessed him with flower Dogwood and that is when they started dating.
As usual, Sakura and Ino keeps on fighting and competing, and now Ino takes a lot of pride with her blossoming relationship with Sai, claiming she has better love life than Sakura and that she will get married before her, much to Sakura's infuriation. After some days, Sai and Ino attended Naruto and Hinata's wedding ceremony as a dating couple holding hands, with everyone around them admiring their relationship. (Bonus: SaiIno is the only couple that was featured in The last opening of Naruto, Opening 20 (Karano Koroko).)
4- SASUKE SHINDEN: BOOK OF SUNRISE NOVEL
Later, after Ino was hospitalized due to the injuries she had after stopping an invasion, Sai was with her at the hospital all the time. Shikamaru and Chōji decide to visit Ino at the hospital and find that Sai is watching over her whilst she sleeps as he sketches a flower that Ino's mother brought her. Shikamaru and Chōji asks Sai to come with them for some investigation, but Sai remains, claiming that he will leave as soon as he has completed his drawing, however, Shikamaru notices several of Sai's already near-completed sketches in the trash as he exits. Sai intentionally made many half-complete drawings and discarded them before completion because he doesn't want to leave Ino. Shikamaru and Chōji realize that Sai did not want to leave Ino's side and begin discussing how much he has changed from the emotionless man he used to be after he met Ino.
Ino and Sai then got married, and had a wonderful wedding ceremony where Shikamaru and Choji were both so happy for Ino that they cried and wished their sensei, Asuma was there to see Ino. Sai and Ino's wedding ceremony is the only ceremony to have been mentioned after Hinata and Naruto's wedding. Well, that's the end of their relationship's details in the Blank Period Novels. Sweet, right?
NEW ERA: BORUTO ANIME, MANGA AND NOVELS
Sai, now married to Ino is the only male known to have taken his spouse's surname upon marriage, being now a part of the great Yamanaka Clan, finally having a family of his own. This family confronted gossips and prejudice from the villagers, and Ino's relationship with Sai was not well received by the Yamanaka Clan, all due to Sai's dark past in the currently disbanded Anbu Root. Despite all this, they managed to be as happy as ever. It is when he married to Ino and got to hold Inojin in his arms, Sai finally felt free and got control over his own life after years of being a puppet to Danzo.
As Boruto series is the story of the new generation, it's main focus from the Yamanaka Family is obviously Ino and Sai's son, Inojin Yamanaka. (Trivia: It is believed that Inojin's name is a mixture of Yamanaka Clan's customary name prefix "Ino" and the suffix "jin" is reference to Sai's late brother Shin). Sai has already told his son Inojin how his mother, Ino saved him with her shintenshin and how they fell in love, and Sai uses the same method (a hug or an affection) to calm Ino down when she gets upset or angry now. Boruto notes that Sai's only weakness is when it comes to Aunt Ino. According to Ino, Sai has never forgotten their anniversary throughout more than a decade they have been together. Although Ino remains as boisterous as ever, Sai is the sole person that gets Ino to fluster despite how angry or upset she is since beginning and even now.
According to Kakashi, Sai and Ino is the most beautiful couple he could imagine, and they both are so close that it seems they are glued to each other, noting that they are like a peculiar picture. Sai and Ino also often gets teased by their friends because how close and affectionate they are even in the public. Ino takes pride in Sai's ninja abilities and Sai takes pride and is proud of Ino's abilities. Ino is thankful that she moved on from Sasuke (Her childhood crush), because according to Boruto Manga, Ino now she feels bad for Sakura, whose husband, Sasuke visits her only very rarely, noting that she has been living such a perfect love-life that she cannot even imagine having a husband who is hardly at home. She is thankful for Sai, so is Sai for Ino. In one of the Boruto Novel it is stated about Ino:
"Because her husband was the one she knew was the best in the world" ~ 💜
I do not think this much of content, especially for a side-couple is less at all. It's more than enough, It's explained perfectly well. Only people who aren't having an idea on Naruto complete series will question or doubt SaiIno's relationship. So "Random couple", "Ino likes Sasuke because he looks like Sasuke", "Sai is a Sasuke rebound", "Ino lost to Sakura in love-life becuase she couldn't marry Sasuke" arguments are all total crap ~ 💕
AND FOR THOSE WHO SAYS SAI AND INO DOESN'T HAVE CHEMISTRY...
Sai was an emotionless and socially awkward boy who worked for the Root Section, meanwhile Ino was an emotional and lively sociable girl who works at a flower Shop, what else do you see other than the raging chemistry between this root and flower? The flower that baths in sunlight and the roots that grow in the dark! It has everything. They perfectly fits into the Yin (Sai) and Yang (Ino) philosophy Kishimoto seems to have considered when making the couples and friendships. As mentioned above Sai is the only man who can make Ino blush since beginning and even now! Ino had no problem with glomping on Sasuke and hugging him, but Sai calling her "Beautiful" makes her blush - See the difference? They both are perfect for each other. Ino gave colours to Sai's black & white life. Ino was a rainbow when Sai was colour blind. Not to mention they both wear crop-tops with exposed midriff. In addition Sai and Ino is the most affectionate couple who has shown most PDA (Public Display of Affection) content and closest moments together so far. I'd argue they have the most chemistry and couple symbolisms.
I hope its clear how they ended up together now 💕 So again, saying SaiIno is forced or random / Calling Sai a Sasuke Rebound / Saying Ino settled for Sai because she didn't get Sasuke as a plan B / Ino lost to Sakura in love life / Sai and Ino don't have chemistry- is making yourself a huge 🤡, actually an entire 🎪
