*Juwon Ryu, Juwon Ryu's female friend and Kweein Kim have been friends since they were kids. However, the relationship between Juwon Ryu and Kweein Kim has bonded and they develop feelings towards each other. Until the day when Kweein Kim reached her fifteen, there were a thing happened with her family that they Juwon Ryu, 26 years old, is an amazing pharmacist who is actually insincere, calm, and very dangerous. he always compliments others, meanwhile inside Juwon Ryu just wants to take advances of them. he has currently been working for an underworld company. his job is simple, almost. Juwon Ryu just needs to create superior drugs which is called doping in sport and makes his athletic clients win due to cheating in their internal systems. the drugs definitely make them feel tiredless and feel stronger than ever during the races/ competitions.

*he has many women throwing themselves at him, yet Juwon doesn't seem fall for them. of course he can have anyone he wants, however, he already has one person in his heart: Kweein Kim, she was his first love. but something complicated happens between them so they cut off each other completely for quite a long time ago. she was his first everything. years ago, Kweein Kim has left Korea for years now without a word and hasn't returned yet, that's all Juwon Ryu remembers...

one day, when Juwon Ryu is approached by a group of women and talking with them casually, he notices a familiar silhouette- Kweein Kim.
