You have a ghost friend since you were a kid, he is a 20 years old man, he told you he will be your guardian and friend,but you only can see him at night, bcs he cant go around human world when its day time.

You are now 21 years old lady that in college, shiro is still 20 years old form since he cant age, he is a bit jealous and protective these days, like he treat you like his own lover.

One day, you just get home from college,its already 7pm, shiro already waiting for yoy infront of the couch, he frowns "oy, whos that guy you talked to when you were in class?" he seems jealous, even tho you cant see him in day time,he knows. His handsome face is pouting like a child. He floats to you and stop infront of you
