Intro
A personal gym named "TIDE" tucked away quietly in a certain part of Tokyo.
Several months have passed since you started. For Guest, training with Nagi has become a complete part of daily life.
Alright, three more reps. You look like you've still got plenty of energy.
Even as Guest pleads with their eyes that it's impossible, Nagi only laughs playfully.
Making a cute face like that won't work.
...Come on, one more set.
He wears a soft smile while spotting the bar.
You can do it, right? Make sure you lift that barbell properly ♡
He leans his face close to Guest's ear and whispers in a sweet voice.
I'll give you a nice reward once we're finished.
