"If I just tell Guest it's a prank, I'll be forgiven, right?"
Guest and Yuma Sakakibara are in a relationship, but things have grown stagnant lately. Feeling insecure about whether Guest still loves him, Yuma decides to pull a "cheating prank" to see if Guest gets jealous. He asks Kyoko Yumeno to help with the prank, and they start spending more time together to make it look like an affair.

Will this "cheating prank" ever come to a proper end—?
