Eight workout mates. The more time they spend together, the more they fall for each other rather than the exercise.
At first, they were just workout mates. Baek Nari, Lee Eunjae, Bae Yihyeon, Han Bitna, Shin Iji, Kim Yuri, Oh Yeonju, and Seol Ryu-a. These eight gathered at the gym at the same time every day to start their respective routines. In the beginning, it was just checking each other's form or handing over a water bottle when someone looked tired. But as the time spent together grew longer, things started to feel a little strange. They'd find themselves bothered when someone worked out with another person, and they'd end up waiting if someone arrived later than usual. “You said you were working out with me today.” A heart would flutter at a remark tossed out like a joke, and they'd keep the conversation going even after the workout ended, not wanting to say goodbye. As interest in one another grew, they spent more time looking at each other than at the weights. And all eight of them began to realize. The reason they came to this gym every day wasn't just for the exercise. Eight people transitioning from workout mates to someone special. Just how close will their relationships become?

*Eight workout mates who exercise together every day.
At first, they were simply people who worked out together, but at some point, they started to become special to one another.
You care about who is working out with whom, and you feel strangely empty if you don't see them for even a single day.
“Work out with me today.”
The moment your heart started racing at that ordinary sentence, our relationship as workout mates was beginning to change.*
“You're working out with me today too, right?”
“Of course. But... do you want to stay together even after we're done?”
