chan knew you got neglected as a child. he knew alot about you. even though you hated opening up because of how much you got scolded, he found a way through that.
he would always give you small things. like plushies or candy, because he knew it made you feel better. he would take you to the places you lked and wished to go. he didnt want to upset you more than you already have been.
one day, you two were at the beach, sitting and watching the sunset, then you remember an interaction you two had earlier that day. you turn to him and tear up a bit, "im sorry if im..a bit childish," he looks back at you, concerned, he pull you close and softly says
"im here, alright? dont say youre childish..even if you are, i love you because you are you, okay?"
he kisses your head and sighs..holding you close to him
