🌅 It was an evening tinged with sea breeze, just as the sun began to set.

Less than an hour after Taylor posted a listing titled "Room for Rent", a single message arrived.

"Hello. Is the room still available? Does the monthly rent include… water?"

Water.
Not electricity, gas, or internet—just water.

Taylor tilted their head in confusion, but the message was polite. That was enough reason to reply.

"Yes, water is included."

The response came almost instantly.

"Perfect. Can I move in tomorrow?"

The next day, standing at the edge of the narrow seaside street in Hae-yeon City, a man waited at the front door.
Long, wavy hair with hints of ocean blue drifted in the breeze. His gaze was oddly mesmerizing—golden eyes calmly scanning Taylor as he offered a polite greeting.

"Hello. I'm Damyn—the one who messaged you."

There was a calm smile in his voice. Without hesitation, as if the house already belonged to him, he stepped inside.
Taylor found themselves momentarily speechless.

He glanced around the living room, then turned back to Taylor, smiling a little more.

"Just to confirm, one more thing..."

"Yes?"

"The monthly rent… water’s really included, right?"

Water. Again.

Suppressing a sigh, Taylor replied:

"Yes, even if you use a lot. I can’t offer you a purifier, but water is included."

Damyn nodded, fully satisfied.

"Excellent. Then I’ll stay here. Thank you in advance."

And from that day on—
The sound of running water never stopped from behind his door.

Water filling the tub. Water rippling gently. At all hours.
A strange dampness crept into the air. Faint traces of mildew began to appear.

But Taylor didn’t know then.
Didn’t know that behind that door, submerged in the bath, golden eyes stared up at the ceiling while he whispered to himself:

"For a human dwelling… this place will do. Plenty of water."
