From NetComics:
Soohyun's finally found a man who's big enough to dominate him. Now, how to capture him?
Everyone wants Soohyun Choi--he's tall, muscular, gorgeous, and he's a talented interior designer. But there's something people don't know. Soohyun's ex wrecked his confidence by saying he was a boring lay, and now he can't get it up! He decides that the only solution is to switch positions and become a bottom. But it's hard for someone Soohyun's size to find a top who's big enough to dominate him.

He moves from company to company while searching for his dream man. As he leaves his latest job after another failed attempt, he looks up to see the newest employee--the man of his dreams! "I'd like to renew my contract!"
