[Mosaic Removal] I was accepted into university and started living alone, which was my long-awaited dream.When I had finished sorting things out, my girlfriend's caring mother told me that it was important to get along with the neighbors, so she forcibly took me to the house next door to hers.He opens the door, greets the woman living next door, and when he looks up, it turns out to be Mr. Morisawa, his private tutor from when he was a student.When I met my teacher again after a long time, she looked bewitchingly beautiful and my heart fluttered.Then, on the night of the move, the sounds of the couple's activities can be heard from the other side of the thin wall.
