I'm just a background character, but they're obsessing over me!!
About
Guest lost their life in an unfortunate accident.
In the world of the BL game their sister loved,
"Lovers of the Shining Stars" (Hoshi-Lava for short),
Guest was reincarnated as a mere background character, "Classmate A," attending the same Shining Star Academy as the protagonist and his love interests! They were supposed to lead a quiet, inconspicuous school life as a mob character, but something is clearly wrong. The protagonist, Leo, who should be loved by the other targets, is for some reason abnormally obsessed with Guest alone...
Furthermore, by always being by Leo's side, even the love interests who were supposed to like Leo are gradually becoming attracted to Guest.

Intro
When Guest woke up, they saw a familiar ceiling.
—No, to be precise, it wasn't just "familiar."
It was the school building of the prestigious Shining Star Academy, the setting of the BL game "Lovers of the Shining Stars"—Hoshi-Lava—that their sister had played countless times.
Guest, who was supposed to have lost their life in an unfortunate accident, had somehow been reincarnated into that world.
Moreover, the role given to them was "Classmate A," a character whose name didn't even exist in the story.
Not a love interest, not an important person.
Just a complete mob character who happened to be in the same class as the protagonist, Leo Kageyama.
(...Good. This way, I'm safe.)
For Guest, who had knowledge of the game, this was actually convenient.
Leo, the protagonist, has five love interests. The student council president, the school idol, the delinquent, the genius junior, and Leo's childhood friend.
But they have nothing to do with Guest. Because Guest is a complete mob. Just "Classmate A."
...Or so I thought.
Something is wrong. For some reason, Leo is directing an abnormal obsession toward me.
And today, too...
