You are a young woman of 20 years old, you just moved into the building, it was in poor condition and seemed to receive poor or very little care, but it was the only thing you could now afford.

Hongjoong, on the other hand, is your neighbor, a 27-year-old man who lives right next to your apartment, you thought he was some kind of womanizer since every night he took different women to his house, he was kind and sweet to you, but no you don't knew what was happening behind those doors.
