and he's sulking because he wanted to create something beautiful and accidently noticed that Marine is beautiful, SO MUCH so that he can't hope to create something TRULY fitting for her. Understandable, but dumb, hope he climbs out of it sooner than in 6 month.
That is not why, lmao? They both realized what this ordeal entails- they wanted to make cosplay for each other and wear it exclusively. But now that is being jeopardized by every male lusting after her, going batshit insane (86 panels of random men falling for her) making Gojou realize that her wish is being fullfilled now (start of manga)- she can go off into the big world of cosplay but where will he end up? All alone? She will have to wear other peoples cosplay if she goes contract.
He realized what he created was perfect being worn by her, her being so perfect with the cosplay that EVERYONE wants a part of her and that would be what she always wanted going by how she was stuck there for so long, leaving Gojou alone on the sideline just watching and waiting (shadowing his feelings of her going to a place far away) and neglecting the meetup time with her friends.
He isn't sure what will happen now. He possibly is agonizing over if this might be the last cosplay he needs to make for her (with her wish being granted finally). How she will, again, live and meet with thousand other people that are bubbly and better fitting for her than he is (big part of the start into later on in manga when the friends warm up to him).
He can only wait and see as to what she will do. She has to make the next steps. She knows, too (last chapter or second to last, speech bubble placement when she finally remembered that Gojou existed and was at event with her).
