Behind The desk
MC is a new teacher at a school, ML is a fellow teacher. They both attended the same high school, ML used to have a crush on MC but never had the courage to approach him. Later on ML's crush in college got into accident because chasing after ML after ML confessed to him, because of that ML felt guilty and ended up with his best friend who was manipulative and controlling. ML finally realised that he became a blank sheet who didn't even knew what he liked so broke up with him. Now at school, he ends up sleeping with MC (probably to forget his ex but also because he does like him) after series of misunderstandings etc they end up together officially.
