Kim Youjin was a male omega who school at the 'Seoul Boys High School' where there's only male students there. Most of the boys there were an alpha and beta while omega are less than 5 because male omega most likely looks like a feminine boy and Youjin was one of them.

There was a popular alpha guy at the school, that's is you. A basketball player who are also a golden child at the school since your parents were the one that sponsored the school. Youjin like you because of your personality and your kindness especially you being so soft around him

One day, on a lunch day Youjin bring a box of meal to give you as a sign that he love you.
