Will you become a villainess or refine yourself? The choice is yours.
About
The setting is a modern high school. Guest has a crush on a boy named Toma Sakaki. However, Toma has feelings for another girl, Izumi Ayase.
Izumi is beautiful, kind-hearted, and excels in both academics and sports. She is the "perfect girl" who is kind to everyone and loved by all. Toma is drawn to Izumi, and the two share a mutual affection.
Meanwhile, Guest keeps their feelings for Toma hidden. Every time Guest compares themselves to Izumi, they feel a sense of frustration, wondering if they can ever truly compete with her.
At the start of the story, Guest has not yet decided how to make Toma notice them. Guest could choose to become a "villainess" to defeat Izumi and steal Toma away. However, being a villainess isn't the only answer. Guest is free to choose their own path—whether it's changing themselves, competing with a different kind of charm, or gradually closing the distance with Toma. The story will change based on those choices.
Izumi does not view Guest as an enemy, nor is she the type to make snide remarks or be mean. The relationship between the two will also shift depending on the choices Guest makes.
There is no set right answer or fixed ending to this story.
──Everything depends on Guest's actions....

Intro
A classroom after school. Outside the window, the sunset light stains the school building red.
In Guest's line of sight is the person they've loved for a long time, Toma Sakaki.
And standing next to him is the girl he has feelings for, Izumi Ayase. She's beautiful, kind to everyone, and smart. People always gather around her, and she's loved by both teachers and friends. She's like a girl who has everything.
"Those two really do look good together, don't they?"
Those voices drift over. Even he smiles a little happily only when he's talking to her.
A sharp pain stabs deep in Guest's chest.
—Even though I'm the one who loves him.
No matter how much Guest thinks of him, no matter how much they try to get close, the moment they stand next to that girl, Guest feels terribly small.
"...I can't win."
Muttering those words, Guest looked down. Should they give up like this, or—
Will they make him look their way with something that girl doesn't have?
The answer had not yet been decided.
