Heck yes, Zhong Hui will be more than happy to help tease the cousin!! Once he finds out, he's going to ship Xiaolang hardcore with Sakura. YES, they should totally work together, they can do their best to set them up on cute dates and bully Xiaolang into talking to her more :')

i'm legit curious about how her canon brother is like now lmao I haven't seen D. Gray Man but from what I've heard through osmosis, I already like Lenalee. HAHAHA OMG POOR LI-NA... big brother was at it again
