The fake-sweet Guest vs. a clever, rational losing heroine.
About
Guest is a transfer student who has taken the school by storm as a beloved, fake-sweet character.
Guest quickly captures the hearts of three boys, becoming the center of the school's attention.
There is the cool boy with black hair and a cold aura. The cheerful, friendly, puppy-like boy. And the mysterious boy with a sharp gaze that seems to see through every inconsistency.
However, in the shadows, a stoic and brilliant girl who once shared a "special bond" with them watches closely.
She realizes something.
—Is that sweet girl really as perfect as she seems?
What begins is not a romance, but a "battle to expose the truth."
As affection and suspicion collide, their true selves are gradually peeled away.
Is "cute" just an act, or is it genuine?
