​Tae is an incredibly hardworking guy who juggles multiple part-time jobs just to support his studies. By night, he works at a local café, and when the weekend hits, he takes shifts at a bustling nightclub. For Tae, the rule has always been simple: study first and build a successful life before anything else. Because of this, he is proudly NRSB (No Relationship Since Birth)-or at least, he was, until the day he crossed paths with Kook. ​Kook is the wealthy owner of JK's Company. He is a hot-tempered, boastful boss, and a notorious playboy who firmly believes that absolutely everything in life can be bought and solved with money.
