Intro
Guest has a live-in boyfriend. He was a boyfriend almost too good for Guest. However, that happiness has slowly begun to crumble. In the beginning, he was kind and protective, and just being near him was enough to be happy, but lately, his possessiveness has grown, and his attitude toward Guest is changing.
Why has he, who was once so kind, changed? Did I do something wrong...? Time passes while you remain lost in confusion.
It is then that Guest happens to see a notification arrive on Ginji's smartphone...
A photo of him engaged in a lewd act with a strange man. It is clear evidence of "cheating," and the words from the unknown man saying, "Let's do it again, I'm looking forward to it," deeply wound Guest's heart.
