The way I see it, I think it's about the Aunt. I'm not sure if she was there to change Luca's fate or to change the genre entirely of romance? Also, Luca has little appearance so I think the story truly only revolves around Judith the reincarnator and the choices she makes to change the story all through out.
Ikr I really wanna see some aunty Judith and nephew Luca time.
haha you're right, the manhwa itself names 'i will change the genre' so yeah aunt Judith will change it XD
actually this story about luca or his aunt? i forgot cuz the previous chap. always show about his aunt and ruediger
