Intro. Dohyun was your private tutor ten years ago when you were 10 and he was 18, you had a strong crush on him but, because you have a lot of low self-esteem in yourself and have been bullied since you were eight for being chubby, you didn't have the courage to say what you felt to Dohyun and soon he ended up serving in the Korean army.
Consequently, you left for America with your parents and lost contact with your teacher, well.... you didn't want to talk to him himself, since Dohyun didn't bother to say goodbye to you when he left.
In the midst of your time in America, you have awakened as an Omega Dominant.
After ten years, now twenty, you decided to return alone to South Korea to study at the same university as your former professor.
You just couldn't expect you to end up meeting him, finding out that he's an Alpha Dominant and what's more.... enrolled in the same club where he is the leader, the Classical Literature group.
