In-Suh, Yeon-Ho, and Da-El, were always together during their school days. In-Suh, who injured his hand in an accident, gives up his dream of becoming a pianist and goes into hiding, but Yeon-Ho suddenly appears in front of In-suh. In-Suh pushes Yeon-Ho away because he is compared to him, but somehow he continues to be swayed by Yeon-Ho

"I've hated you since high school, if it weren't for Da-El..."

"Kim Da-El, who you were desperate for, is getting married to another woman."

In-Suh suddenly hears the news of Da-El, whom he liked, is getting married. And...

"...I endured it for 8 years-"

I get to know Yeon-Ho's hidden feelings...
