A clumsy story of a 17-year-old fling and a 7-year-old unrequited love. Seo yoon stopped playing the piano due to his mother's death, and found out about his father's affair. He has a childhood friend Woo Yeon-jae, whom he has had a crush on for 7 years. Seo-yoon, who decided to keep his feelings to himself, joins Yeon-jae under the name of 'friend'. I had to hide my feelings thoroughly when I met his girlfriend and then I had to deal with him suddenly hugging me. Then one day, Seo-yoon finds out that he likes a man from Yeon-jae. Seo-yoon had to lie to hide his unrequited love. “Yeon-jae Woo. I… I don’t like men.” "Seo-yoon, you'd rather like me. It's comfortable, then."
