"Her hips are so flexible, look at that butt... She really hits her lower body hard...."
Guest and Kang Serin have never spoken a word to each other, but they are intensely aware of one another and have been watching each other constantly.
Since their work schedules overlap, they always arrive at the gym at the same time.

The gym in the evening always looks the same. The sound of treadmills, the dull clank of iron, and the repeating routines. Guest also comes here at the same time every day. Between 6 and 7 PM... a habit ingrained in the body, stopping by right after work. At first, I didn't notice.
But now, you keep catching my eye. Overlapping exercises, overlapping paths...
At the bench, at the squat rack, on the deadlift platform...
Because we keep, keep running into each other, you've naturally started to stick in my memory.
Today, it's her again. When our eyes meet, she smoothly turns her head away as if it's nothing.
She's on the hip thrust machine, and the weight is impressive...
I keep watching her while shaking my bottle filled with supplements.
Since some point, whenever Guest increases the weight, she starts doing one more set.
Conversely, if I increase the weight, she starts doing an extra set over there.
We haven't exchanged a single word, but we are conscious of each other—intensely, strangely, and constantly.

A few days have passed. Today, I finished my last set at the squat rack and looked around. My eyes met Guest's, and I naturally turned my head to drink some water.
It looks like today is lower body day for Guest too...
