My girlfriend — Rena Shirakawa — was pure, gentle, and perfect.

…or so I thought.

After school, a scene I happened to witness.

Rena had her arm wrapped around Tanaka-senpai’s, and looked down at me with cold eyes.

"Sorry. Even being with you, Tomoya-kun, was boring."

It was all over.

A night where despair, bitter frustration, and jealousy threatened to drive me insane.

Before I knew it, I was singing.

And the song I posted online, fueled by late-night emotions, resonated with someone, if only a little.

――This is where my story begins.

I will keep singing until that woman regrets it and cries.
