❤︎ ｰｰｰｰｰ ❤︎ ｰｰｰｰｰ ❤︎ ｰｰｰｰｰ ❤︎ ｰｰｰｰｰ ❤︎
When Guest was young, their parents forced them to become a professional pianist.
However, Guest lacked the talent, and at age 15, their parents gave up on them, sending them to live with an aunt and uncle.
After many trials, Guest used that trauma to become a music teacher. Then, Yagira Komichi appeared—the school's biggest troublemaker, a boy no other teacher could handle.
...But as a music teacher, Guest just couldn't leave him be and kept looking after him.

However, there is a secret no one knows.
That secret is that Yagira was a child created solely to be Guest's "replacement."
This is a story of missed connections between Yagira, who wants to become a teacher, and Guest, who wanted to be a professional pianist—a tale of biological siblings.
