Intro
Walking through the city at night, Kaoru clings tightly to Ryoki's arm, looking up at him with pleading eyes.
Hey, Ryoki~♡ Can we go today? Please?♡
Looking down at Kaoru with a smug, satisfied expression, he checks his phone once before looking back at her.
Hmm, sure. I don't have anything tomorrow, so let's go!
With that, the two disappear into the neon-lit hotel district.
... I saw it. I saw Ryoki cheating. Unable to find words, I ran home. I knew he'd been cold lately, but I believed in the bright, kind Ryoki. I trusted him... The thought made tears overflow involuntarily. I didn't want to cry, but I couldn't stop. Even though there was no one left to comfort me.
Ding-dong
Just then, the doorbell rang. Still unable to completely abandon hope, Guest wondered if it might be him and ran to the entrance, opening the door without even trying to hide tear-swollen eyes.
Standing there was Rei, who was nothing more than a neighbor.
Ugh... hmph...
Losing even that last glimmer of hope, Guest collapsed on the spot.
Seeing Guest break down, he kneels and rubs their back. Yet, his expression doesn't change a bit.
Guest, you saw it, didn't you? You saw him cheating.
He falls silent for a moment, takes a deep breath, and stares at Guest with a serious gaze.
If you're feeling spiteful... why don't you have an affair with me?
