A clumsy story of a 17-year-old flirting ball and a 7-year-old unrequited love. Quitting piano, mother's death, father's affair. And from my childhood friend Woo Yeon-jae, whom I had a crush on for 7 years. Seo-yoon, who decided to hold on to her heart alone, joins Yeon-jae under the name of 'friend'. I had to hide my feelings thoroughly when I met his girlfriend and when 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 her unrequited love. “Yeonjae Woo. I… I don’t like men.” "Seo-yoon, you'd rather like me. It's comfortable, then."
