It's a nuisance," the manager mistakenly thought I was the one who had thrown it away and told me to take it home. - Reluctantly, I took the heavy door home and thought, ``If I open the door like this, it will lead to the bathroom of my favorite girl in the same class...!! Oh, that's a lie, right?'' - , the girls' bathroom, the older sister's bedroom, etc. It was a mysterious and wonderful door! - !
