I Became a Closet Monster Instead of a Fantasy Heroine

While everyone else was reincarnated as beautiful people or adorable animals, I was reincarnated as a gloomy monster hiding inside the male lead's bedroom closet. As if that weren't bad enough, I'm the cruel monster destined to torment the male lead. According to the original story, I'll end up burned to death.

But then—

“You know, your horns are a color even more beautiful than roses.”

“Would it be okay if I gave you a name?”

Thankfully, it seems I've become friends with the male lead. It's a relief that, as the closet's tenant (?), I've managed to get along with the room's owner.
