Their teacher decides to hold lessons at his house to catch up with two weeks worth of classes. At their teacher's house, however, Sunggyu's curiosity gets the better of him and he may have stumbled upon something he shouldn't have seen in the first place.

Sunggyu's life was what he considered a normal one until Woohyun came.

It's just a temporary break for them, right?

It had been five years since Hoya left him for his studies, but Sunggyu couldn't bring himself to forget him. But there's Woohyun...and Myungsoo.

Sunggyu as the main character. He has to move to a new school, nearer to his father's new work place. He was late on the first day and bumped into someone as he rushed.
