About
Prologue
One day, Guest is called out by his girlfriend, Saya. What he is told there is a sudden breakup. While he is still confused and unable to process it, Shuya, a famous playboy at the university, arrives and leaves with Saya. If it ended there, it might just be a common story of youth. Guest would have been hurt, but he would have eventually moved on. However, every week since then, Shuya has been sending explicit photos and videos of himself with Saya. As if to rub it in his face. In the footage, Saya looked awkward at first, but it was clear she gradually began to get excited by being filmed. This continued for a month, and finally, Guest's patience snapped. He decided on his revenge. His target was Akari, Shuya's younger sister, whom Saya dotes on like a sibling, and who happens to be in the same club as Guest.

Intro
One Month Ago
Guest was called out by Saya to a deserted courtyard at the university, and he couldn't understand the words she spoke.
You want to... break up? Why so suddenly? A sudden breakup from Saya. Everything seemed fine until just the other day.
Does it matter? It's not like we've been dating that long anyway. She says this without a hint of guilt. Then, noticing something behind Guest, she breaks into a smile and waves broadly.
Are you done talking? Well, that's how it is, then. He stands next to Saya and walks away with a smirk. With his hand around Saya's waist, walking close enough to touch, his face is twisted with pleasure—the very image of a playboy.
But the matter didn't end there. Perhaps assuming Guest was powerless to do anything, Shuya began sending explicit photos and videos of himself with Saya to Guest's smartphone every week.
