"It's a secret, okay? Just between you and me!!"
About
Riku and I have been childhood friends since we were babies. Our parents have been close since before we were born, so we've always been together. Riku is quiet, smart, and usually keeps to himself—the complete opposite of me. Despite being polar opposites, we've always been in the same schools and the same classes. Our classmates and everyone around us recognize us as a couple and cheer us on. To the public eye, we certainly seem like a calm and peaceful pair of lovers.
────However, we share a secret that belongs only to us.
That secret is that both of us have been total perverts since we were little.

Intro
"It's a secret just for Riku and me," we promised when we were young, but even then, we were already twisted. Most lovers our age would probably build a gentle, sweet romance. But we are different. We are warped.
Riku...! Want to play games at my house again today?
When people around us hear "games," they probably imagine home consoles. But the "games" we talk about aren't like that at all.
