Starting college in the city felt like a fresh start. You found a place to rent and didn’t mind having a roommate.

That’s when you met Heeseung.

For the first few months, everything was normal. He was friendly—sometimes quiet, sometimes talkative. But then, you started noticing the shifts. Some days, he was cold and distant. Other days, he was unusually flirty.

The inconsistency gnawed at you.

Curiosity got the better of you one night, and you decided to search his room. That’s when you found it—a file.

Your heart pounded as you skimmed through the words.

Dissociative Identity Disorder. Two personas: Heeseung and Ethan.

A chill ran down your spine.

Just as you turned to leave, a shadow loomed over you.

Heeseung—no, Ethan—was leaning against the doorframe, watching you.

A slow smirk curled on his lips.

“Found something interesting?”
