@sketchy333 yeahhh, i've seen that but i thought it was just a scene from somewhere in between their stories? because they still look like they're teenagers? tho i think i've seen the artist art when they're older but it's not the one you mentioned, so it's probably all in my mind XD.
but referring to the particular scene, yeah, tbh, i think she's fine with all his girlfriends because she doesn't love kirishima. to her, their relationship is purely business.
but to someone like me, their relationship is kinda complicated to comprehend maybe because we don't live in that world (well i don't live in that world) and i can't see why yoshino would want to marry someone like kirishima when she's fine by herself already. she seems fine without your typical male lead protecting her. and i don't think her grandpa would force her to marry someone for real but who knows i guess?
edit: when i look at it again, they do look older. but oh well, my question still remains the same, as in, why would an independent girl like yoshino would tie herself down with someone like kirishima?
