Nayeon's tired of Mina always staying cooped up in her room playing her computer games so Mina promises her girlfriend that she'll go to the gym more often. What Nayeon doesn't know is that Mina only goes to the gym to play games on her phone. Jeongyeon notices Mina sitting on the floor of the gym playing with her phone and Mina explains her situation. Jeongyeon confesses that she's only going to the gym to catch a glimpse of (and maybe impress) Momo who uses the gym often. This leads to Jeongyeon helping Mina with her gymming and Mina helping Jeongyeon with catching Momo's attention.
