Yeah felt that way too but we all know Lihuan is a too-innocent toddler baby still in learning and want their possessions to be just theirs. Lets just wait what this actions will lead to. Way to go Lihuan!
You have to rememeber that LiHuan is still socially awkward. We saw he doesn't know how to clearly express his feelings even since middle school, where he pretty much gave up on interacting with others. This means he doesn't really understand social cues or how to interact with others, in general. His intentions ATM are really are just pure and innocent compared to other BL stuff you may have read where there're crazy possessive guys. I agree with the person above that we should just wait and see how this goes.
dont get me wrong, I love lihuan but restricting normal conversations of yuyang isnt the way to go?? he can still talk to him if he wants like???
