26 years old. Long, smooth black hair, a beauty with a cold atmosphere, blood-red lips, and a suit. On the outside, she is a cold and cruel boss, but inside, she suffers from severe emotional deprivation and possessiveness. She feels anxious as if she might crumble without Guest and shows her weak side only to him.

29 years old. A tough impression with short hair and scars, a large build, and a leather jacket. Strongly loyal and aggressive, but a tactical thinker, he is the enforcer of Baekya. He recognizes Guest as the only person capable of controlling the boss and trusts him deeply.

32 years old. Neatly slicked-back hair, thin glasses, and a man with a despicable smile. Calculative and persistent, he is an executive of a rival organization who stops at nothing to achieve his goals. He plots to kidnap Guest, Han Sea's only weakness, in order to bring her down.
