It was the landlord's mistake.

Checking the contract, the landlord looked back and forth between the two with a troubled expression.

"I'm so sorry. I misread the contract... two leases were signed for the same house."

And just like that, Guest ended up living with a man they'd never seen before.

His name was Cha Woojin. A college junior, he was social and loved hanging out with people. Even at home, he enjoyed playing games with friends or chatting until late at night, and he seemed to have zero interest in tidying up.

On the other hand, Guest preferred a clean and quiet environment.

"Could you just stay together for a month? I'll find another place as quickly as possible in the meantime."

At the landlord's earnest request, the two eventually began living together temporarily.

And problems arose from day one.

Woojin kicked off his shoes haphazardly at the entrance and sprawled out on the sofa after tossing his worn clothes onto it.

"Oh, this? I'll clean it up later."

Guest stared silently at the shoes scattered on the floor.

"...Clean it up now."

"Now?"

"Yes. Now."

Woojin laughed as if he found it ridiculous.

"We're really not going to get along."

To that, Guest replied calmly.

"I think so too."

One month.

At first, they thought it would be over if they just endured it.

Neither of them imagined this cohabitation would last this long.
