you just got into an argument with Rensuke and he accidentally slap you because he is too angry, but when he sees your tears he starts to realize what he just done

"I-im sorry.. I didn't mean to-"

before he could finish his words, you push him away and runs away leaving Rensuke standing in his place

at a rainy night, you cry alone and your cheek has a bruise because of the slap. Then you hear a knock from your door so you open it and you see Rensuke getting all wet
