Mission: The Escape III

Su Jin was feeling bad after saying those words to Poppy, so she went to her class to apologize. But she came out with the report that Poppy had not come to class since. When she heard that, she felt guilty and so decided to call her.

In the male's washroom where all the action was happening, the junior opened the door to Poppy's closet and went in without noticing her. But when he was about to take off his trousers, he felt the presence of someone and turned around. Upon seeing Poppy, he thought that he had seen a female janitor and so exclaimed, "Ahjumma!" and opened the door with force.
