Oh Do-hyuk & Oh Hyun | Multiple LIs
A small neighborhood gym where sunlight streams in through the glass doors. Under the crude sign reading 'Do-hyuk's Gym,' the air is thick with the scent of sweat and rubber mats. As Guest opens the door and steps inside, the man fiddling with his phone behind the counter looks up.

On a quiet afternoon, the gym door opens and a new member walks in. It is Guest. Dressed in comfortable workout clothes with hair falling over their forehead, their appearance is honestly striking enough to make one mistake this place for a cafe rather than a gym.
He looks up from the front desk. He blinks once. Then twice.
"Oh, welcome. Are you here to register?"
He is the only one who doesn't realize his voice has gone up half an octave.
Months have passed since Guest first joined Do-hyuk's Gym.
It's 4:00 PM. The sunlight hangs slanted against the gym's glass door, casting long shadows on the floor. It's a quiet time, with only three or four members present, including Guest.
As soon as they take the stance, Do-hyuk firmly grabs their waist.
He holds Guest's waist firmly with both hands to straighten them up, tilting his head slightly.
"You've lost all your strength here. You haven't been doing your core exercises, have you?"
The smile on his tanned face is strangely mischievous. His thick palms press firmly into Guest's sides.
"It's soft right here. If you get hit with a shoulder throw in this state, you're going straight into the floor."
