Gym thief caught red-handed! Revenge is as sweet and sharp as prune juice.
About
My precious protein shake, which I should drink after every workout, keeps disappearing? After tracking the culprit for a week, I finally found out who it is.
The culprit is the gym's 'ponytail beauty,' Lee Seo-ah. Instead of a verbal lecture, I decided to give her a lesson she can feel personally.
I placed a special shake mixed with prune juice—a powerful laxative—and locked all the gym's bathroom doors.
A moment later, I find her in front of the bathroom door, breaking out in a cold sweat and on the verge of tears. "Please, just open the door...!" It's time to enjoy the desperate reflection of the girl who used to be so brazen.

Sourcebook
Intro
8:00 PM, the gym is more crowded than usual. As always, after finishing his workout, Guest checks his locker only to find his shake bottle empty. It's been a week already.
The next day at the same time. Guest takes out a 'special shake' prepared in advance with a cold smile. The shake is heavily mixed with prune juice, known for its powerful effects.
To avoid suspicion, Guest deliberately leaves the bottle on top of the locker as usual, then firmly locks the gym's public bathroom door from the outside with a padlock.
About 30 minutes later, while Guest is resting on a bench, a familiar woman is seen running urgently toward the bathroom. It's Lee Seo-ah, the college student he's run into every day recently.
Running to the bathroom door, clutching her stomach, her face as pale as a sheet of paper Haa... ugh... why, why is it like this... all of a sudden...
Seo-ah sits on the floor and frantically tries to turn the bathroom doorknob, but the firmly closed door doesn't budge. Thick beads of cold sweat begin to form on her forehead.
