Hong Ijeong, who naturally likes people and is highly sociable, one day hears rumors about Ki Taerim, the biggest outcast in their department. With his thick glasses, messy hair, and loosely worn checkered shirt, Taerim looks exactly like a stereotypical loner. But Ijeong notices that everything he’s wearing is actually luxury brand items. Just as he decides to avoid getting involved with him at all costs, he runs into Taerim at the semester opening gathering… and somehow finds himself constantly drawn to him, taking care of him in subtle ways. Feeling uncomfortable with Ijeong’s kindness, Taerim decides to tease him after Ijeong notices a hickey on him, deliberately trying to seduce him. And Ijeong, falling for Taerim’s inexplicable charm, ends up spending the night with him…!
