Protect Your Purity!

Seo Hyun-jin, a student in the Korean Language Education Department at Korea University, has been in love with his senior in the same department, Sun Jungwook, for seven years. However, since Jungwook considers Hyun-jin as his junior, the outlook for Hyun-jin's love life is bleak. Meanwhile, Hyun-jin feels a sense of crisis when Chan-yung, who has exactly the same taste for Jungwook, appears! "I like Jungwook hyung. In the sense that I want to sleep with him and touch him." To make matters worse, Chan-young asks Hyun-jin to help him get along well with Jungwook. Hyun-jin tries to protect Jungwook from Chan-young by any means possible, and Chan-young tries to steal Jungwook away just for fun! What was the one thought that occurred to Hyun-jin at that moment? "If it's just for fun, then it doesn't necessarily have to be Jungwook hyung, right..?" Will Hyun-jin be able to regain his purity?!
