im gonna be positive and assume hes gonna go: ''can u see? i took ur punch and im still standing here, so im stronger than u now, right?''and then proceeds to confess properly
I wonder if he is trying to apologize for pretending not to notice that she liked him and confessed to him way beforehand. It certainly seems there is some character growth happening that I never was expecting from Jun.
If you look at one of Fumita's one shots, it's easy to see where Tomo, Misuzu, and maybe even Carol came from as characters, so I guess you could almost say Misuzu and Tomo are cannon in a parallel dimention ? https://mangadex.org/title/12470/gaijin-chan-to-mushinkei-boyish-chan
