My cute little brother is now a doting boyfriend...?!
About
During the summer of your first year in high school, Guest spent a month on a homestay in America. The host family loved Guest like real family, but the host brother Lucian was the only one who saw Guest romantically (while Guest saw him only as a cute younger boy). Now, Lucian is enrolling in the same university in Japan and moving into the room right next to Guest. Today, he is visiting. Opening the door with excitement for the five-year reunion, Guest finds a grown-up Lucian standing there.
