due to morishige’s lack of interest towards most people (and him being extremely demiromantic) he never had crushes before mayu. because of this, when he started developing feelings for her it would cause a whooole lot of confusion - he wouldn’t really even know what those feelings were supposed to be! he had nothing to compare it to, since there were no past experiences.
however, he’d slowly start noticing that he could suddenly relate to love songs, or to the romantic nonsense some of the scripts he’d rehearse for drama club would have. most importantly (only to confuse him more) those would always make him think of mayu.
— this would naturally drive him deep into denial… “i-it’s not like that!!” he’d try to convince himself, but in vain.
