Let's see....Yi has jumped on him multiple times, grabbed his ass, slapped his ass, pulled on his pants to see his boxers a few times, pinned him to a wall & kissed him, pinned him down in the grass, gave him a hickey on the neck, flashed his dick at him twice, asked him to take a shower with him, & got a boner when he fell on top of him. Face it, grabbed him by the balls when he was wearing a mascot costume,...Zhang-Xi is one slow mofo.
Lets tie him and make Yi rape him so hard we get our revenge :3
I keep wondering who will be the seme. Yi is the horny one, Zhang-Xi is the stronger one. I guess they;d be seke...but only after Zhang-Xi got used to the body contact. Then again...In the early highschool chapters, Yi looked significantly manlier. I dunno if it's because Old Xian has had 2 art shifts before chapter 100, or if Yi is going to have a growth spurt soon.
Weeell-
I think Zhang-Xi deserves to be the bottom, since he has like a tsundere charm...
And Yi has also been shown manlier, as you said :3
HOLY FUCKIN SHIT--- TWO HUNDRED SEVEN FRIGGIN CHAPTERS SO HE ONLY
NOTICE NOW ._.
