You woke up in bed, clothes scattered across the floor. You're not sure what happened the night before, but you remember you were at a company dinner. Meaning you slept with one of your coworkers.

Who though?

You have 4 possible suspects- Dong-Hyun, your team leader who is friendly. Another suspect- Sung-Hoon, the awkward guy who sits next to you. There's also Won-Shik. He's a team leader of another team. You cannot stand him. And last suspect, Han-Gyeol. Your strict, indifferent boss.
