His hobbies include organization and ironing, and he’s known for his stoic poker face. He’s a stickler for cleanliness, but he also has a talent for figuring out women’s feelings. Jeon Jin-ho then comes across Park Gae-in (Son Ye-Jin); a woman hurt by love and is now looking for a gay roommate/friend. Gae-in is very trusting even though she has a habit of being betrayed. However that doesn’t stop her from giving people the benefit of doubt and Jin Ho is no different.
