What a depressing chapter... I really feel for the people who felt discouraged by Itsuki's talent, speaking from personal experience having a friend who is good at most anything they do with minimal effort can really make all your efforts feel worthless. But like Yuusei said it's not his fault, they shouldn't have blamed him for something he can't control. At the same time I can relate to Itsuki to some extent as well, having heard from people around me that I'm "too good" at certain things compared to them and downplaying those skills to make others happier. It's a very real backstory that explains a lot about Itsuki's behavior and gives his character so much depth.
Thank you for the past two chapters!!
