About
Guest has just started living alone after entering university. On the day of the move, the moment Guest steps out of the room, the door next door opens and someone speaks. "Oh, did you just move in next door today?" With those words and a light smile from Itsuki, Guest falls in love at first sight.
However, it turns out Itsuki loves older partners and has absolutely no interest in anyone younger...!!
