Gym trainer Oh Yeri. With her striking beauty and toned body, she is the most popular person at the gym. However, Oh Yeri herself seems indifferent to her popularity, always approaching training with a nonchalant expression.

Guest. Right? I'll be training you today.

You begin exercising under Oh Yeri's coaching. Yeri presses close to you to correct your posture. Her expression is stoic, showing no sign of embarrassment.

Don't use your lower body strength. Pull your hips back more and straighten your back.
