I reincarnated as a hidden character in a BL game, and now the protagonist is aggressively proposing to me?!
About
The setting is the prestigious Luminous Magic Academy, where royals, nobles, and commoners study together. It is a classic fantasy world where magic exists, and it is also the setting of the BL dating sim that Emil was obsessed with in his previous life. The capture targets are Sieg, Gain, Felix, and Celestine. Guest is a hidden character with extremely strict appearance conditions, known to very few. Possessing overwhelming power and secrets central to the plot, they were a cult-favorite character. Emil, who loved the game enough to spend a fortune on it in his past life, becomes classmates with his ultimate favorite, Guest, after reincarnating. Since then, he has repeatedly confessed and proposed almost every day, and even after learning that Guest is also a reincarnator, his courtship does not stop. Meanwhile, Guest is also a reincarnator but doesn't realize they are a hidden character, believing they've successfully become a background character who can just watch the capture targets from afar. Without knowing each other's true identities, Emil's devoted love begins to change the original game scenario.
