Lan WangJi looked at him, “Why do you suddenly remember to ask about this?”

Wei WuXian, “Just say it. What was its name? I think I might’ve guessed how you recognized me.”

"We already know its name." said Nie Huaisang.

"How?" asked Wei Wuxian.

"Your son said it." said Nie Huaisang.

"When?" Wei Wuxian asked again.

"In Dafan Mountain." said Jiang Cheng.

"What? Why do I don't know about that?" asked Wei Wuxian.

"We don't know either." said Jin Zixuan.

"Your memory is really bad when it comes to Lan Wangji." he added.

"You're not helping, peacock." said Wei Wuxian.

"Because I will never help you." said Jin Zixuan.

On the night at Dafan Mountain, the tune that he somehow played was precisely the one, when he had been fevered under the Xuanwu cave in Dusk-Creek Mountain, Lan WangJi had hummed beside him!

Lan WangJi refused to say anything. Wei WuXian hurried him, “Say it, what song is it? Who composed it?”

Lan WangJi, “I did.”

Wei WuXian, “You composed it?!”

Lan WangJi, “Mn.”

"Wow! Lan Zhan, you're so talented." said Wei Wuxian.

"Can you compose more songs?" he asked.

"Mn. I can." said Lan Wangji.

"That's great. You'll compose a song and we'll play it together." said Wei Wuxian.

"But, what is the name of that song first?" he asked.

"Let him find it out on his own, Lan Wangji." said Jiang Cheng.

"Jiang Cheng." Wei Wuxian whined.

"So that you'll learn to remember everything related to him." said Jiang Cheng.

"Oh." said Wei Wuxian and grinned.

Wei WuXian had thought that it was a secret song of the GusuLan Sect. Now that he knew, he was both surprised and overjoyed. What he was surprised about was quite obvious. What he was overjoyed about, though, he couldn’t really tell. He guessed, “If you really did recognize from just this, it must’ve meant that—this song, you’ve never let anyone else hear it?”

Lan WangJi, “Never.”

"It's only for you, a-niang." said Sizhui.

"Really?" asked Wei Wuxian.

"Mn. A-die's ode of love for you." said Sizhui and his parents blushed.

"So sweet." said Jiang Yanli with a tease.

"Yeah, my Lan Zhan is sweet." said Wei Wuxian while blushing so hard.

"So sweet that your thick face can't take it?" asked Jiang Cheng.

"Shut up!" Wei Wuxian exclaimed.

Wei WuXian was so happy that he kicked Lil’ Apple. Lil’ Apple shouted in anger, kicking its hind legs as though to shake him off its back. Just in time, Lan WangJi pulled the rein tight. Wei WuXian hugged Lil’ Apple’s neck, “It’s fine, it’s fine. That’s just how it is. It only kicks a few times. Let’s continue. Then, really, what is it called?”

Lan WangJi, “What do you think?”

Wei WuXian, “What do you mean what do I think? Just does it have a name or not?” In his heart he muttered. Would Lan WangJi’s style of naming things be the same as Jiang Cheng’s? That’d be impossible! He asked, “Are you asking me for my opinion? I think that why don’t you call it…”

After the more than eighty names he had come up with were all refused by Lan WangJi, Wei WuXian’s spirit finally began to dwindle.

"It already have a name." said Nie Huaisang.

"Just tell me." said Wei Wuxian.

"It's related to the both of you." said Jin Zixuan.

"I know that." said Wei Wuxian.

"Just give up." said Jiang Cheng.

"You three aren't helping me." Wei Wuxian whined.

"Want a clue?" asked Jiang Cheng.

"Yes, yes, yes." said Wei Wuxian.

"Fine. It starts with a Wang and ends in Xian." said Jiang Cheng.

Wei Wuxian looked at him dumbly.

"What is that?" he asked.

"See, he's intelligent in everything but not in this." said Jiang Cheng.

"I can't believe it." said Jin Zixuan.

"There's no name that started with that and end with that." said Wei Wuxian.

"You're so dense!" the three exclaimed.
