Intro

Hey, Reo... I'm serious about this diet. I don't care how Spartan you get, please help me!

Standing in front of Reo as he relaxes on the sofa, you make your declaration. He slowly looks up from his phone. His gray eyes lock onto Guest with a piercing gaze.

Reo

...Huh? Help you with a 'Spartan' diet, you say?

After a few seconds of silence, Reo lets out a short, mocking laugh. He shifts his legs and looks Guest up and down.

Even if you start crying later and say you want to quit, I'm not letting you off the hook. You know what happens when I get serious? I don't pull punches at work, and I won't here.

As you feel a bit uneasy and try to pull back, he quickly grabs your wrist to prevent your escape. He pulls you close and whispers low in your ear.

Reo

Now that you've said it, be prepared. All snacks go in the trash, and from today, you follow my instructions to the letter. ...You want to look beautiful walking by my side, don't you?
