Maybe Yuri likes him more then we think :D Yuri is my favourite character and i reeeallyy hope that there will be chapter about his past :3
Maybe Yuri wanted also to be loved (whoever he is or whatever he has become) and maybe it's connected to his background story that I'm really looking forward to know as well. I'm really rooting for Yuri and Jimmy.
I think youre right! I think Yuri is completely capable of being normal (i mean...he aint stupid considering hes the top rank in his class). Maybe he lost respect for himself or got bored of his normal life along the way, and started to act like a sex crazed idiot who cant talk properly. Maybe Fujisaki was the only one who conveyed the love that Yuri truly wanted, which may be why Yuri snaps out of character when hes with Fujisaki
i wonder why Yuri is so fond of Fujisaki despite him being a stalker and how he doesnt really stand out.. its really great to see that their relationship has progressed, and i really hope we get Yuri's background story soon! it mind explain why he acts (kinda) normal around Fujisaki.
I also loooove Kashima x Toono, but if Yaachan fell in love with Toono first, I think I would have ended up liking Yaachan x Toono more. (but I think we all have a feeling that Kashima x Toono and Yaachan x Tamura is most likely end game)
