Undefined XX

[The man he mistook for his lover's affair partner is his new team leader?!]
Chi-won and Ji-hyeok first meet at a hotel under awkward circumstances. They each view the other as "the person they want to avoid most" and "the most interesting person," respectively. Coincidentally, they meet again at work—this time, as direct supervisor and subordinate!
This is a cute story about their chaotic, bumbling, hate-filled rivalry transforming into a sweet and loving relationship.
