All St Ann's students knew that Reese loved Shelf.

Reese,as the youngest member of one of the eight families of S(a country), he has two older brothers and one older sister, all of whom are fond of him.

Shelf, the second son of another family, have been good friends with Reese since childhood, and they go to school together every day, play ball together, fight together, are good friends who talk about everything.

However, Reese has a secret that he loves his friend. He tested Shelf's attitude toward gay, and Shelf showed extreme disgust, so Reese had to hide it in his heart, afraid that they would never be friends again.

Until they were about to go to college, Shelf told him he was going to another country to study music for three years. Reese didn't understand why Shelf hadn't told himself until now. Aren't they best friends? Still, Reese smiled and said, "Well, don't forget me, you sinner."

During these three years, Reese gradually distanced from Shelf, since Shelf was always busy. Despite he attempts to connect, after countless failures, Reese thought, perhaps it was time for him to give up.
