"You're going to teach me the number one's technique, right?"

Seri, the most popular top at a gay sex shop, is one day rescued by a newcomer, Renya, when he is being harassed by an enthusiastic customer.

When I told him I would treat him as a thank you, he asked me to give him a lesson on how to entertain, and I agreed to give him advice.

Renya says, "I'm worried because my ranking isn't going well," but he has a sweet look and a smart manner of acting, and there's nothing about him that would make him seem worried.

While he was teaching him the techniques and harboring doubts, Renya suddenly flashed a provocative smile, pushed Seri down, and tried to forcefully embrace him...!?
