SakuKage Stacey's brother AU
- Stacey's brother by Mad Tsai but Stacey's is Kiyoko.
- Kiyoko and Sakusa are step siblings.
- Sakusa for whatever reason has to move in with Kiyoko
- Sakusa, Kageyama and their training camp crew kept texting after training camp and formed a friendship.
- Kageyama starts going to Kiyoko's house to hang out with Sakusa
- The first years know this but the second and third years don't
- Tanaka gets jealous whenever this happens
- This isn't helped by Tsukishima
- Tanaka and Nishinoya confront the other first years (when Kageyama isn't there) and Tsukishima decides to be Tsukishima and mess with Tanaka by claiming Kageyama has a crush on Kiyoko
- Tanaka and Nishinoya believe them
- Because Kageyama is at Kiyoko's house so often, they actually do become somewhat friends.
- Kageyama and Kiyoko don't know Tanaka and Nishinoya think Kageyama has a crush on Kageyama
- Tanaka starts to think Kiyoko might like him back
- Meanwhile Kageyama is developing feelings for Sakusa
- Hinata and Tsukishima tease him about this
- Yamaguchi and Yachi are supportive and enourage him to tell him
- Tsukishima either forgets he told Nishinoya and Tanaka Kageyama had a crush on Kiyoko or just assumes they'll learn the truth eventually and doesn't correct it.
- But Tanaka and Nishinoya tell Yamamoto, who let's it spill to Nekoma and soon its making the rounds of the volleyball teams that Kageyama likes Kiyoko.
- Only it becomes a kind of Chinese whispers where somewhere along the line it becomes Kageyama and Kiyoko are dating
- Other Karasuno students also believe they're dating and it basically becomes common knowledge
- Sakusa manages to hear this and gets jealous and confronts Kageyama.
- Kageyama is completely confused, denies the rumors, and inadvertently admits his feelings. He hooks up with Sakusa. They start dating shortly after
- Kiyoko also learns of the rumors about her and Kageyama. She doesn't deny or confirm. People believing she's dating Kageyama has kept her more persistent suitors at bay and she knows the truth will come out eventually.
- it comes to a head at a game when Kageyama and Sakusa are found making out before or after a game. They think they're in a more private spot than they are.
- Lots of people are pissed because they think Kageyama cheated on Kiyoko, including Tanaka and Nishinoya.
- Kageyama yells at Tsukishima a little for lying but isn't really mad.
- Sakusa and Kageyama come forward with their relationship, they don't really have a choice.
- I do imagine this leads to Tanaka going to Kageyama for advice on Kiyoko, and Kageyama is a little confused but tries to play wingman.
- Whether that's successful or not, Kiyoko and Tanaka do end up together
