It feels like Gojo is feeling guilty because even though he loves Hina dolls and has always wanted to be a doll maker, he also really likes making cosplay. The Haniel event where he saw how much everyone loved Marin and his outfit made him wish for the first time that he could do that for the rest of his life.
That could be why he went to the Hina event; partly to remind himself that he already has his life mapped out. There isn’t room to do both. And finally we find out one of his secret worries is that he won’t be able to show his grandfather is true skill before he passes on. That might be why he’s so dejected - cause of course he can’t change his mind about his life plans when he’s been gushing about following his in his g’pas steps (๑•ㅂ•)و✧
So...we not gonna get AU Soo-Young as a college student and Tae-Seung as a TA/Professor? Or a historical side story where Min and Soo-Young grew up as close friends/brothers turned lovers? How about blind date AU with the busy, hotshot CEO Tae and exhausted software developer Soo-Young who also happens to work at his company? Sensei PLEASE. You have so many good options .
I wish there was an official English release :(
