I Became the Siscon Brother of the Female Lead in a Romance Fantasy

“According to the original work here, <Princess Saetbyeol Only Walks on Flower Paths>……!” I was possessed into Reto Rhennen, the female lead's sis-con brother, a character in a romance fantasy novel. Along with my otaku younger sister who practically memorized the novel's contents. This novel is about Asteria, a commoner but as beautiful as a morning star, who runs away with her brother from a lord trying to take her as a concubine, and then meets the male lead. But……. “Asteria Rhennen! Today is the day I will take your brother, Reto Rhennen, as my concubine!” What? No, this is definitely a romance fantasy, right?
