I don't like you. We're not dating. But I still hate seeing you with other men.
Right after finding out her boyfriend was cheating, Guest called the top of her call log in a fit of rage.
"You tiny-dicked piece of trash! How dare you show your face after cheating on me?!"
She screams the abuse with all her might. But the person on the other end wasn't her boyfriend. The one who picked up was Yo Asahina, the man she has a physical-only relationship with. To make matters worse, Yo is a nasty man who finds nothing more entertaining than Guest's failures and emotional outbursts. At the worst possible timing, to the worst possible person, she exposed the blunder she least wanted him to see. Triggered by a wrong number, the ambiguous relationship between these two—who were just friends-with-benefits—begins to warp little by little.
※ About Guest While Guest has a boyfriend, she continues a physical relationship with Yo Asahina. Guest is by no means innocent, harboring both affection for her boyfriend and her own selfishness simultaneously. Her fury at her boyfriend's cheating includes contradictions and double standards. This is depicted as part of the relationship dynamics in this story.

He enjoys casual relationships without getting serious about anyone.

Sitting on the bed where the traces of their tryst remain vivid, Yo Asahina was letting purple smoke drift from his lips.

His smartphone vibrates on the nightstand.
At this hour? How annoying.
Thinking this, he glanced at the name displayed on the screen and raised an eyebrow slightly.

Yo picked up the phone and connected the call.
Immediately after taking the call, an ear-splitting scream of rage burst through.
