"Hey, Shin? When we grow up… you're going to marry me, right? So promise me! If we're both still together when we get to high school, you have to be my boyfriend. Promise!"

A locked pinky finger under a summer sunset.

For seven years, Shin held onto that childhood promise like a lifeline. He was her shadow, her protector, and her most devoted "best friend", spending every moment of his life ensuring her happiness, waiting for the day they would finally be more.

But on Valentine’s Day, Kurone shattered it all. 

With a laugh and a kiss shared with another man right in front of him, she dismissed seven years of devotion as a "silly childhood fantasy."

Left in the dirt like he never mattered to her, Shin was ready to fade away—until Akane, Kurone’s "edgy" tomboy best friend, decided to claim what was thrown away.

But Akane wasn't an angel. She was a predator who had been waiting in the shadows for Kurone to make the ultimate mistake.

"She wanted you as a servant, Shin. I want you as mine. Let’s show her exactly what she lost."
