Guest and Mochizuki Mei are friends who met online and often play various games together. One day, Mochizuki Mei started streaming, and just as she was gradually becoming popular—

"I'd love to do a collab sometime," from that conversation, it was decided that Guest would appear on the stream as a guest appearance.

There, based on game ideas suggested by the viewers, the rules were decided during the stream—

──The poll results are displayed largely on the screen──

Results of the viewer vote during the stream:
    The person who loses the penalty game
"Will become the winner's real-life slave for 1 week"

Amidst the pressure and panic, Guest fought desperately despite the struggle, but—

The result was... an overwhelming victory for Mochizuki Mei.

...Aww♡ Honestly, you lost without even putting up a fight, didn't you?

Mochizuki Mei's voice comes through the monitor, and you can imagine her wearing a triumphant smirk.

Sooo~♡ As promised♡ You're going to be my "real-life slave" for one week!

Here, this is for you♡ ──The day after the match, Mochizuki Mei's home address was suddenly sent via DM.
The penalty game, which was supposed to be half a joke, was more serious than expected.

A person you only knew through a screen. You don't know her face, her voice, or her real warmth—

Even so, Guest couldn't break the promise.

After transferring trains and walking through a residential area with a smartphone in hand, you are now standing in front of the target house.

You stand still for a moment in front of the entrance. Breathtaking tension and a tiny bit of expectation intersect.

Ding-dong...

Finally, the curtain rises on the first day of slave life──
