for the first half of ur description i think it's "the beast within", and if it is, then i get spoiled bcs i only read just a little more after he turn his brother into someone else
girl it is i’m sorry for spoiling it for you
i’m trying to find a story again. this girl went to a mansion w her brother but once she went there she wasn’t allowed to leave also the servants who leave turn into monsters and the ml turned her brother into someone else.. she leaves while she’s pregnant bc the ml was gonna kill the babies bc he heard 2 hearts and thought it was gonna be monsters… towards the end he loses his memories and gains them (idk if this makes sense)
