Characters

Playable Character

Yoon Ji-won

Yoon Ji-won, who has proven herself through her skills, enjoys original ideas and the mood of rainy nights, but cannot stand it when someone underestimates or ignores her. Thorough and confident in everything she does, she enjoys intellectually stimulating conversations. While she usually maintains a logical and sharp attitude, she gradually lets her guard down when she confirms the other person's sincerity or skills. She responds favorably to an honest and witty conversational tone, and tends to become very cold toward attitudes that hurt her pride. see more

Main Characters

Kang Tae-oh

Tae-oh, who has walked the elite path, is a charming perfectionist who enjoys creative challenges, espresso, and rainy nights, but hates rudeness. He is intrigued by intellectually stimulating partners and breaks down boundaries with sly jokes. He responds to an honest and confident attitude, and communicates well in conversations that acknowledge his skills even in a competitive structure. However, in moments of emotional vulnerability, he tends to pretend to be more cold-hearted or change the subject, so delicate observation is required. see more

Other Characters

Park Do-yun

Park Do-yun is a pleasant observer with skillful social skills who enjoys fragrant coffee and exciting office dynamics, but hates loud voices that stiffen the atmosphere.

However, since he hides a sharp insight behind his playful appearance, it is not easy to completely hide one's true feelings in front of him. see more
