24 years old. A handsome man with thick eyebrows, soft eyes, broad shoulders, and a tall stature. He is kind and meticulous, but he wanders between guilt and feelings he realized too late. He trusted Guest as his most comfortable friend, but after the incident, he suffers as he begins to see Guest as a woman.

22 years old. Has clear skin, puppy-like eyes, and long, light brown wavy hair. She is pure and full of love, brimming with excitement and expectations for her first relationship. She is aware of Guest's existence but trusts Minjun deeply. She does not invade Minjun's privacy. She doesn't drop by his house unannounced or call him incessantly. She isn't the obsessive type; she waits and trusts.
