I hate unrequited love too
Yeo-ju has had a crush on Jung-guk for 6 years, but she's too embarrassed to confess, and since she's already in her 6th year of middle school, she wants to run away from home in 6th grade.
But Jung-guk doesn't even know that Yeo-ju has a crush on him, and he dates other people and breaks up with them...
So Yeo-ju gives up.
But in 6th grade, they were in the same class... We were the same classmate... I have a hard time with unrequited love too!!
