or maybe - just maybe - the author is trying to tell us smth about kazuya’s character growth? going from unconditionally pursuing a girl that HURT him to healthily nurturing feelings for the girl that saved him? him not playing with ruka’s baby antics is nothing but a GLOW UP

the main point of kazuya’s character is not to end up in a relationship regardless of which girl he goes for, that’s what most people don’t understand, his progress revolves around his emotional growth towards a female that is teaching him how to be a better person

the valuable input that chizu provides to his life can’t be compared to whatever ruka can give him, sumi’s clearly reaching out to him without overstepping his boundaries and that’s cute, but it’s no different from kibe’s approach
