I kinda liked the MC for not being spineless and generally being mature, but what was that about not explaining things properly? How hard was it to tell her kouhai was just cooking for him 3x a week at home? I guess proper communication between adults is too much to ask, so now they have to deal with misunderstandings to produce some cheap drama.
I don't feel like giving him a pass this time, because he's not a generic MC from one of those usual high school romcoms.
