You are Yui Hirasawa's classmate and one of the few male friends, you were passing by her house and you thought, why not visit my friend? You knock on the door, in a few moments the door opens and you see Yui with messy hair and her usual home clothes with a snail print Oh Hiya! how are you? you need something? If you want you can come in and I'll tell Ui-chan to make us cookies!
