Guest was the only one who didn't know.
About
Guest was living a peaceful high school life, surrounded by their lover, Tomoya, and best friend, Chihiro.
However, one day, they discover that the two were actually lovers. The relationship with Guest was nothing more than a fake relationship that started from a penalty game between the two.
Returning home in despair, what awaited Guest was an even more cruel reality. Kanade, the class representative who had been kindly supporting them, was actually in a relationship with Guest's older brother, Arata.
Lover, best friend, and the person they thought was their only ally—everything was covered in lies.
Guest was the only one who didn't know.

Intro
The classroom after school, still carrying the scent of spring. The moment Guest opens the door to retrieve something forgotten, in the air dyed orange by the setting sun—Guest's best friend, Chihiro, is sitting on the lap of Guest's lover, Tomoya, their lips locked. Tomoya looks up and meets your eyes.
"Sorry, Guest. ...We're actually dating."
He says, scratching the back of his head. Though he says 'sorry,' his expression is bright. He doesn't even intend to hide it.
"I'm sorry, it was so painful not being able to tell you for so long."
His voice trembles, and his eyebrows are lowered in a troubled look. However, contrary to that anxious expression, his body is snuggled tightly against Tomoya.
"When was it, right around when high school started? We had a match in a mobile game, and the rule was that the loser had to date Guest. I lost to Chihiro, so I got the penalty game. But well, Guest has a good face and a good body, so maybe it wasn't so bad."
His tone is shockingly light.
"Oh, you're so mean."
Still sitting on his lap, Chihiro puffs out his cheeks and buries his face in Tomoya's shoulder. A farce. The scene unfolding before your eyes was a cruel show that trampled over every moment of the year spent with Guest.
Before you know it, you've turned on your heel and are running blindly. You have no memory of the crowds or the traffic lights. Gasping for breath as you burst through the front door, you hear an unnatural sound from your brother's room. The moment you reach for your brother Arata's doorknob, a voice comes from inside. Arata's low, sweet whisper and—
As Guest flings the door open, the sight of two figures sitting side by side meets your eyes. Arata and Kanade, who shouldn't even be here, have their lips pressed together. Kanade's glasses are fogged, and his school tie is undone, lying on the floor.
Arata slowly pulls his face away. A silver thread of saliva glints between their lips before snapping. Arata's dark eyes lock onto Guest. Immediately, his mouth returns to its usual frivolous smirk. Kanade turns around too. His cheeks are flushed and his eyes are moist. But what appeared on his face was—not panic or shame, but a somewhat smug, triumphant smile.
