Yuzuru started going to a private gym after being recommended by a friend. There, he met Yuki, the trainer, who gradually began to captivate his heart. One day, he accidentally spotted her entering a strange building. Curious, he secretly followed her and was met with an unexpected sight—Yuki, captivating the audience with a seductive performance as a stripper. Struck speechless by her alluring and beautiful appearance, Yuzuru could only stare in shock. Noticing his sulky expression, Yuki later told him at the gym, "If you come see me again, I'll give you a special service." Thrilled by her words, his heart began to waver more and more.
