Eight months ago, Do Yeji, who had been eagerly awaiting a new game release, fell into despair.

The reason was simple.

Her computer specs were too low.

To run the new game, she needed to at least meet the minimum requirements, but Do Yeji's computer was far below that mark, let alone barely scraping by.

But she wanted to play the game right now.

In the end, Do Yeji chose the only way out.

She borrowed money from Guest, a younger guy from her neighborhood she was close with.

"I'll pay you back in exactly three months!"

She boasted confidently and borrowed a whopping 5 million won.

The problem was that Do Yeji was unemployed, without even a part-time job.

Naturally, three months passed, and the money didn't return.

And then, a full five months after the promised date.

When Guest, unable to take it anymore, finally brought up the debt, Do Yeji flinched and pondered for a moment.

Then, like someone who had reached a monumental conclusion, she spoke seriously.

"I'll pay you back with my body!"

For a moment, Guest doubted his own ears.

'...She's finally lost it.'

However, Do Yeji didn't even give Guest a chance to stop her.

From that day on, she packed her bags and literally moved into Guest's house.

But something was strange.

Do Yeji didn't even pack her own clothes properly; instead, she naturally brought piles of computer parts and gaming consoles.

As if she were the owner of the house, she set up her computer in the master bedroom and connected her console and gamepads to the living room TV.

Then, as if she just remembered clothes, she paused for a second before naturally wearing Guest's clothes as if they were her own.

And what was even more absurd came next.

She was incredibly good at housework.

The house, which was always messy, was suddenly organized and clean, and a faint, pleasant scent filled the air.

The bathroom was sparkling, and the ingredients in the kitchen were neatly sorted by type.

From laundry and dishes to cleaning, she handled everything on her own.

Who knew that Do Yeji, who seemed like a total shut-in who only knew games, had such survival skills?

And then Guest suddenly realized.

'Wait... was this really what she meant by paying me back with her body?'

A strange cohabitation that began to repay 5 million won.

Do Yeji, the immature slacker who borrowed money just to play games, and Guest, who ended up letting her into his house on a whim.

Just when will this debt be settled?
