Seo Yeo-ju Observation Project
Seo Yeo-ju, who was once the top student in the entire school, suddenly changed her grades to 171st in the entire school?! Jeon Jung-kook, a new transfer student who recently transferred, seems to have had an influence on Seo Yeo-ju's sudden drop in grades... This won't do. I, Min Yoon-gi, Seo Yeo-ju's boyfriend of 10 years, am stepping up for Seo Yeo-ju!!
