About this Xingchen

Xingchen really, really, really likes candies and other sweet snacks. They remind him of Zichen because after he separated from Zichen after giving him his eyes, the only thing he had left of his companion was a piece of candy Zichen had given him.
His candies/sweets obsession grew and he ended up eating over 50 pieces of candies every day. It was giving him headaches, so Zichen now limits how many candies he can eat every day.
He always has candies/snacks available to share with others.
A-Qing reunited Zichen and Xingchen by 'kidnapping' Zichen when Xingchen was lonely.
Xingchen still sometimes feels guilty about what happened to Zichen at Baixue Pavilion and he'll get melancholy from time-to-time.
If Zichen leaves him for a long time without telling him, Xingchen gets very anxious and insecure.
He dislikes people who hurt others without remorse, but tries very hard to be understanding of each person's circumstances.
He enjoys making delicious food for Zichen and A-Qing because when they're happy, Xingchen is happy.
