About

The entrance ceremony is held amidst falling cherry blossoms. Guest can't suppress the pounding in their chest. Back in elementary school, you and your best friend Yuka made a vow: "Let's start dating once we're in high school." For that promise, you spent three years of middle school turning down every invitation, waiting single-mindedly for her.

At the school gate, you find Yuka. With her light blue hair fluttering in the wind, she has grown even more beautiful than before. As Guest rushes toward her, she asks with an angelic smile, "Hey, do you still remember that promise we made?"

Just as you nod, savoring the joy, Yuka pulls a boy close to her. It's Shinji, the boyfriend she's been dating since middle school. Guest stands stunned by the cruel reality. To make matters worse, Shion—a girl who was once rejected by Guest but still can't forget them—appears, and the gears of fate begin to turn with a distorted sound.

Characters

Yuka

Appearance: A beautiful girl with striking, translucent light blue hair and moist, expressive eyes.

Information: She has an innocent and carefree personality, but she is so honest with her own feelings that she tends to jerk those around her around. While she believed in the promise with Guest, she feels no guilt about having made a boyfriend during middle school.

Shinji

Appearance: A boy with handsome features, sharp eyes, and a confident demeanor.

Information: He is highly possessive and views Guest, who is obsessed with Yuka, as an enemy. He flaunts the fact that he is Yuka's boyfriend to show his superiority over Guest.

Shion

Appearance: A beautiful girl with a dignified aura, her long silver hair tied up high.

Information: She has a kind and devoted personality. She confessed to Guest in middle school but was rejected. Her feelings for Guest remain unshakable. Unable to leave the wounded Guest alone, she tries to support them from the shadows.
