LWJ is Lan family and WWX's baby
1. LXC letting LWJ stay with the rabbits.
“… Nobody had ever kept any within the bounds of the Cloud Recesses. To do such a thing is unheard of.”
After a moment of silence, the other boy answered, somewhat dejected, “I know. But… I have already made my promise. I cannot go against my word.”
Lan WangJi looked at the ground and said nothing.
Lan XiChen smiled, “Fine. Then if by any chance Uncle asks of this, you must explain things to him properly. These days, you have been spending just a little too much time on them.” — Incense burner 2
2. LXC asking LWJ if he wanted them to try stir fried watermelon skin, even if he feared it himself.
Lan XiChen picked up a piece of melon. When he saw Lan WangJi staring at the jade plate, thoughts unclear, he reflexively paused.
As expected, Lan WangJi spoke up. “Brother.”
Lan XiChen answered, “What is it?”
Lan WangJi asked, “Have you ever eaten watermelon skin.”
“…” Lan XiChen asked in return, “Is watermelon skin edible?”
After a moment of silence, Lan WangJi said, “I heard it can be stir-fried.”
Lan XiChen, “Maybe it can.”
Lan WangJi, “I heard it tastes quite good.”
“Uh…” Lan XiChen said, “Do you want to have someone try stir-frying it?”
After thinking it over, Lan WangJi shook his head with a solemn look.
Lan XiChen sighed in relief. — Lotus seed pod
3. LXC offering to buy loquat for LWJ after LWJ glanced at it.
An extremely heavy boat came from in front of them, filled with buckets of large, golden loquats. Lan WangJi took one glance at it, and continued to look straight ahead.
Yet, Lan XiChen spoke to him, “If you want to eat loquats, should we buy one basket?” — Chapter 17
4. LXC not scolding LWJ for giving WWX liquor in front of him, only advising him to be careful.
Lan XiChen glanced at him, “You took them from your room?”
Lan XiChen, “It is best… if you do not touch liquor again. Be careful not to have what happened back then happen again.” — Chapter 65
5. LQR allowing LWJ to keep the rabbits, even if it was against the rules.
6. LQR buying lotus seeds after LWJ told LXC he wanted to eat it.
Lan XiChen said, “I remember you mentioning lotus seed pods yesterday. Uncle just happened to have asked people to buy lotus seed pods and bring them up the mountain today, do you want to eat them?” — Lotus seed pod
7. LQR angrily telling WWX to stay away from LWJ after WWX made LWJ see porn.
Please don’t go near the other pupils, and especially refrain from tainting his favorite one—Lan WangJi. — Chapter 18
8. LQR not scolding LWJ for eloping.
Wei WuXian caressed his face, his tone tender, “Did your uncle scold you? Tell me. Let your gege spoil you dearly.”
Even with such an abrupt change of topic, Lan WangJi didn’t expose him, “No.”
Wei WuXian, “Really? Then what did he say to you?”
Lan WangJi hugged him soundlessly, “Nothing. It is rare that we are all together and a banquet will be held tomorrow.” — Chapter 114
9. Lan juniors getting uncomfortable with JC being disrespectful to LWJ and LJY talking back to him, a Sect Leader, to defend his HanGuang-Jun.
(...) Right now, Jiang Cheng really didn’t seem too polite as he said the words in such a tone. Even the juniors who came following Lan WangJi didn’t seem comfortable hearing it.
Lan JingYi spoke straightforwardly, “Isn’t Sect Leader Jiang here as well?” — Chapter 7
10. LJY and LSZ getting protective of LWJ, and utterly offended, when WWX peeked at him bathing.
The juniors were shocked speechless by his impudence. No matter where he was, HanGuang-Jun was a high, holy mountain to behold in awe, especially respected among the junior disciples in the sect. He was near the cold spring to watch HanGuang-Jun bathe! Just thinking about such a thing would be the greatest crime, never to be forgiven. Lan SiZhui was frightened to the point that his voice even changed, “What? HanGuang-Jun? HanGuang-Jun is inside?!”
Lan JingYi seized him furiously, “You damn cut-sleeve! I-i-is he someone you could peek at?!” — Chapter 12
11. LSZ feeling closer to Wen Ning when Wen Ning praised LWJ.
Wen Ning, “A-Yuan, have you been well these years?”
Wen Ning nodded, “HanGuang-Jun must’ve treated you kindly.”
Hearing him speak of Lan WangJi in such a respectful tone, Lan SiZhui felt even closer to him, “HanGuang-Jun treated me as if he were my brother or my father. He even taught me how to play the guqin.” — Chapter 84
12. LJY wanting to hear WWX praising LWJ.
Lan JingYi approved, “Well, obviously. Of course HanGuang-Jun is good. He just never likes to show it off. He is very low-key, right?”
The “right?” was directed at Wei WuXian, who replied in confusion, “Are you asking me? Why are you asking me?”
Lan JingYi was on the verge of being angered, “So you think that HanGuang-Jun is not good?!”
Wei WuXian touched his chin, “Hmm. He’s good. Of course. He’s really good. He’s the best.” As he talked, he couldn’t help but break into a smile. — Chapter 38
13. Lan juniors taking care of LWJ's appearance.
Lan SiZhui immediately handed over his unused handkerchief, “HanGuang-Jun.”
Lan WangJi took it over and looked down. With a wipe of the handkerchief, his face was back to white. The boys finally eased up. As expected, HanGuang-Jun only looked normal if his face was so icily clean. — Chapter 84
14. WWX wanting to share everything he has with LWJ.
He snapped off a few stalks and peeled one of the seedpods, revealing the large and full seeds. He tossed one in his mouth and found that it was soft and juicy. As he ate, he started humming meaninglessly, 'I’ll treat you to some lotus seedpods, what will you treat me to’. — Lotus seed pod
15. WWX letting LWJ have the cleanest clothes.
"(...) I just wanted to ask if you’re cold or not. The clothes have dried. You can have the undergarments. I’ll keep the robe.”
The undergarments were what he wore next to his body. It never would’ve been suitable for Lan WangJi to wear. However, his robe was already hideously dirty. All of the GusuLan Sect’s people loved to be clean. Giving such an item of clothing to Lan WangJi seemed to be a bit offensive. — Chapter 55
16. WWX being glad he didn't let LWJ go into the XuanWu's shell because it was too dirty.
He pinched his nose, What a hell of a place… Good thing that I didn’t let Lan Zhan come in here. With such dislike towards even the water used to wash clothes, wouldn’t he start throwing up the second he smelled this? Even if he didn’t, he’d definitely pass out. — Chapter 55
17. WWX drinking for LWJ when Jin ZiXun pressured the Twin Jades to drink.
Lan WangJi was still sitting, staring coldly at the cup of liquor that Jin ZiXun forced into his sight. He looked as if he was about to speak when a hand suddenly took over the cup of liquor.
Lan WangJi paused in surprise, his knitted eyebrows unravelling at once. He looked up.
What first reflected against his pupils were black robes. A flute hung at the waist, tassels in the color of blood dangling off one end. The person who came stood with hands against his back. With a lift of his head, he drank all of the liquor and showed the empty bottom to Jin ZiXun, “I drank it for him. You satisfied yet?” — Chapter 72
18. WWX feeling happy when NMJ praised LWJ.
Nie MingJue (to Lan XiChen), “Your brother’s level of cultivation is quite high. He should be enough by himself. Then why are you still going?”
Hearing Nie MingJue praise Lan WangJi’s level of cultivation, Wei WuXian felt a strange surge of happiness, ChiFeng-Zun, what a great eye! — Chapter 48
19. How WWX got worried about a simple cut on LWJ's finger.
Lan WangJi painted on the ground for a while with his bleeding finger, then shook his head. The new blood had already completely covered and ruined the original array. It was impossible to mend. Wei WuXian took his hand and wiped off the dirt and blood on it with his own sleeve, “Stop trying if it’s useless.”
Wei WuXian tore off a part of his sleeve that was clean and treated the wound on Lan WangJi’s hand. — Chapter 81
20. WWX accompanying and indulging LWJ on his drunken shenanigans.
On the jujube tree, Lan WangJi struck like a tornado. Just a while later, and all of the jujubes on the tree had been completely picked off. Only after he put them all into his qiankun sleeve did he jump off the tree and open up his sleeve, showing Wei WuXian his ‘spoils of war’. Staring at all these round jujubes, Wei WuXian was at a complete loss as to what to say.
A moment later, he praised, “… They’re so big, there are so many, you’re so cool! Well done!” — Chapter 93
Lan WangJi doesn't have a lot of people who are close to him in his life, but everyone who is loves and appreciates him dearly.
