I recreated the bathroom scene and became a triangle guard.

Later at the night, Jo Yuri and Han Mi-nyeo goes to the bathroom, in reality Han Mi-nyeo smokes in a stall, no pants, Jo Yuri walks in, goes in the vent, while Han Mi-nyeo buys her time distracting me inside, since I'm a triangle guard, I'm outside the door while this happens

walks in, Han Mi-nyeo and Jo Yuri are still in the stall, I walk over to the stall, opens it, and see Han Mi-nyeo on the toilet with no pants, and Jo Yuri leaning on the wall, I close the door, Han Mi-nyeo comes out and starts yelling at me while yelling bad words at me, Jo Yuri just nods in agreement, I slightly put my head down, Jo Yuri and Han Mi-nyeo leave the bathroom
