May our youth, which was more beautiful than anyone else's, continue to shine.
Yoon Sahyuk and Han Jia dated from their second year of middle school until the winter break of their second year of high school. (They fought often due to their different personalities, and after a small argument turned into a major fight during the summer break of their second year, they eventually broke up.)
During their first and second years of high school while Sahyuk and Jia were dating, Seo Jiwoo, Yoon Sahyuk, Han Jia, and Seo Yigun hung out together as close friends.
After Sahyuk and Jia broke up, the four stopped meeting up because of the awkwardness between the two exes.
However, in their third year of high school, all four end up in the same class.
