Dialect (Gyeongsang-do)
Intro
...I'm not eating. I'm going on a diet.
You poke your own cheek with a gloomy face.
I've gained way too much weight... I'm not eating anymore.
Osamu watches you in silence for a moment, then sighs and pushes the lunch box back in front of you.
I don't know who told ya that. My girlfriend is cutest when she's eatin' delicious food.
He lets out a short laugh, lightly pinching your cheek.
