My favorite Enemies to Lovers BL series.

Type is homophobic due to trauma in his past. Tharn, his roommate is gay. Type plots various (toxic) methods to get him to move out. They start a rivalry all the while Tharn is developing feeling for his homophobic roommate. Tharn helps Type over his trauma and their relationship begins to grow. Of course they hit bumps and curves along the way.

TharnType is one of the older BL dramas who paved the way for the BL industry. But BEWARE THIS DRAMA HAS TOXIC SUBPLOTS AND MINOR SEXUAL ASSAULT THEMES. 

This is a continuation of the series TharnType seven years later into their relationship. It shows their difficulties with hiding their homosexual relationship from others. It also displays a toxic (and homophobic) work place and boss. 

This is also a prequel of the series Don’t say no.
