While Others Became Female Leads in Romantic Fantasy Novels, I Became a Closet Monster

When others were reincarnating as beautiful people or adorable animals, I ended up in the body of a creepy monster living in the male lead's closet. According to the original story, I would be burned to death, but... "Your horns are more beautiful than roses. Can I give you a name?" The male lead doesn't seem to be scared of me at all. I thought it was fortunate that I, now a tenant (?), was able to get along with the male lead, the owner of the room. (Source: Naver, translated)
