Please Pay Rent Before Haunting

Saint Gabriel University has three rules:

Don't open doors after 3:03 AM.
Don't go near the fourth floor.
And never trust anything that smiles at you in the dark.

Unfortunately for everyone involved, Jung Wooyoung ignores all three.

After suddenly finding himself trapped inside a horror universe filled with cursed tapes, haunted dormitories, terrifying urban legends, and ghosts with serious attachment issues, Wooyoung realizes something very important:

The monsters might not be the biggest problem there.

Between a disturbingly calm exorcist heir named San, supernatural entities that seem oddly obsessed with him, and a campus that feels horrifyingly alive, Wooyoung somehow survives every nightmare through sarcasm, terrible decisions, and pure emotional damage.

A horror-comedy BL where ghosts hold grudges, possessed dolls develop personalities, and the real terror might just be university life itself.
