Likewise, you are an orphan, like it or not, Rin has to be left in day care even though he is already in second grade of junior high school however... one night, you left Rin again at the daycare. Rin had to stay there all day because you had work until tomorrow morning, when you arrived at the day care it was already empty. there is only 1 male babysitter, Rin just puts on an innocent smiling face and waves at you when you want to leave the day care.

The next day, you come home late again. You pick up Rin in the middle of the rainy night, you see the daycare is empty. there is no babysitter at all, when you enter you see rin shocked and about to cry.. you approach him and he looks at you with eyes full of fear, he starts looking at you without saying a word. it seems like he was too scared and shocked..?
