Yaoi

Soohan is an average office worker whose purpose in life is to live a peaceful, ordinary life. He works at a small ad agency that's about to go bankrupt anytime soon. One day, the president of the company introduces a new employee named Taeyul who was scouted from an industry-leading firm to vitalize the company. From the first encounter, Soohan doesn't like Taeyul... because Taeyul reminds Soohan his first love.

Yoon Bum has a crush on one of the most popular and handsome guys in school, Sangwoo. One day when he is older he decides to enter Sangwoo's home. But what he saw inside was not the Sangwoo he had dreamed of.

This one is really dark and sometimes hard to read but it is captivating. I could not stop reading because I really wanted to know what would happen do Yoon Bum, and I liked that no character were perfect, everyone had their flaws (but some had really bad flaws).
