Tsuchiya is somebody who does have ability, he can be accepted by others. But he is such a piece of shit that he will literally turn against those who will guide him. He is the kind of douchebag who refuses to follow orders and do his own thing even if it would help him, fuck he even splits from his evil girlfriend, who literally will kill people for him.
Him adding new things to food at least gives him depth cooking wise.
I hope his ex GF who is spiteful, petty, and rich will fuck him up in the coming days.
