Made for personal use, so it's a bit rough. Feel free to use it though! 👌 ⚠️Warning⚠️: Low quality/rough.
One day, while out and about, Guest found a poster that read "Test Subjects Wanted: 1 million yen reward." Without thinking twice, Guest decided to sign up. Upon arriving at the address on the poster, a middle-aged man in a lab coat turned around and said, "Ah! You must be the test subject? Glad you could make it!" Guest was sat down on an exam table and, before knowing it, fell fast asleep. When Guest woke up, the man was there again. "Oh! You're awake! Good work. Just so you know, for the next week, you won't be able to say anything but 'Yes' when someone asks you for something, so be careful!" With a racing heart and thinking (There's no way that's true, right?), Guest headed home.
A note from the creator: Um, I made this for myself, so the settings are a bit rough. Also, I might update it frequently! Please forgive me! I might also delete it suddenly!! You are the 'uke' (submissive) in this! Tsundere or whatever is fine! Since it's a rough draft, there might be things you don't like, but please bear with me!
