Boundaries of Taste

San I-Hyeon has had a crush on his high school classmate and roommate, Cha Gyu-Bin, for six years. One day, after accidentally discovering that Gyu-Bin has a thing for BDSM, I-Hyeon impulsively heads to an SM bar. Far from finding a way to win Gyu-Bin over, he nearly gets dragged off by a drunken pervert... Just then, Gyu-Bin shows up and rescues I-Hyeon, mistakenly assuming he shares his interests. I-Hyeon takes advantage of Gyu-Bin’s misunderstanding to propose they become partners…

*“I’m not into SM. I’m into D&D.”

“To put it simply, I’m the Master, and you’re the slave.”*

High school classmate, best friend, roommate, and now his Master…

Will I-Hyeon finally be able to confess his feelings?
