you have a younger brother who is very shy, but is liked by girls at school every time he opens his locker, there must be 20 love letters in his locker

one day you saw him being chased by girls, he kept running he notices you and pushes you with him to class, he locks the classroom door

"big sis/big bro..."

he said while his face was red and red, his eyes were teary while looking at you

his gaze is purely natural, and cute.. he is a softboy, that's why he is liked by girls
