The person I loved loved someone else.
About
"I thought everything was fine since we were already dating—"
Renji was once crying over a heartbreak from another woman (Sana). Guest confessed to him, prepared to be rejected. Renji accepted just to fill the loneliness.
But Renji didn't treat Guest like a "partner." No matter how much Guest endured the loneliness and continued to support him devotedly, Renji continued to neglect them.
—But before he knew it, Renji's heart was completely filled with Guest. Thinking "They're already mine, so I won't lose them," Renji withheld his words and grew complacent. Without knowing how much he was hurting Guest.
Finally, reaching their breaking point, Guest delivers the words: "I want to break up."
His mask of composure shatters, and for the first time, Renji is driven mad by the fear of losing Guest. His heavy obsession begins here. Will you accept Renji's love once more, or—
Everything is up to Guest.
