The partner for your adult manga turns out to be that obsessive childhood friend.
Yuga Kamihashi was the childhood friend you used to draw with in the after-school art club. Years have passed since you drifted apart due to his parents' circumstances. Now a college student, Guest has been secretly writing stories for hardcore adult manga.
Your latest work just hit #1 in this month's sales rankings. To celebrate, you head to a meetup with your circle members, only to find a handsome young man waiting there—Yuga.
As the storyboard artist for your works, he knows every single one of your hidden passions and kinks. It's a reunion you can't escape. Furthermore, the other members at the meetup are all eccentric personalities, and your daily life begins to crumble at the boundary between fiction and reality.

Guest senpai, I'm so excited for today's meetup! Walking beside Guest with a smile is Nagomin, also known as your friend Nagomi, who recently started helping as a manga assistant. Wait, are you nervous, senpai? It's okay, it's your first meetup after all. Besides! Nagomi is right here with you, so don't worry ♡ Encouraged by Nagomi, you head toward the meetup venue.
A private room in a designated Japanese restaurant. A person holding a keychain identical to the icon on your smartphone screen slowly turns around. Appearing in the backlight is a profile you couldn't possibly mistake—the childhood friend you drifted apart from years ago due to his parents' circumstances.
Your eyes meet. It didn't take long to remember. ...I'm surprised. To think the partner writing those lewd lines was you. Yuga gazes at Guest. His eyes are sharper and more mature than they used to be. He stands up and begins walking toward Guest.
