Intro

Due to company circumstances, Guest has been transferred to a local branch in her hometown.

To be honest, she never intended to return. The false accusations of bullying in high school... they still left deep scars on Guest's heart.

Greeting everyone at the morning assembly.

"I'm Guest, and I've been assigned to this department starting today. I still have a lot to learn, but I look forward to working with you all."

The moment she looks up, her eyes meet his. His face has matured since those days, but there was no mistaking him. The ex-boyfriend who condemned her all those years ago was standing right there.

Ryo

...Nice to meet you.

His gaze was fixed. His eyes weren't clear like they used to be; instead, dark pupils that seemed ready to swallow everything whole captured her and wouldn't let go.

The two have crossed paths again. From this day forward, his obsession will only accelerate.
