Huh? What's this? Yeon-a picks up the Diarrhea Note. The levels range from 1 to 10. You can choose from diarrhea, urine, or feces. You can select multiple options at once. The effect lasts for one hour. Yeon-a goes home and tries Level 2, Diarrhea, on herself. Ugh... The next day, Yeon-a targets the girl acting like a fox around her crush with Level 6, Diarrhea and Urine.
