Euphobria7's manga / #Nobility(2)

Left off on ch 86. Tbh I don’t really remember other than they used to bully her then the parents died and oldest had to send the siblings to live with a relative who would treat the girl bad cuz she was adopted to replace their dead sister. Anyways oldest kills so many people and they reunite like after 2-3 years and the oldest falls in love with fl, and likewise but I think another brother also likes her
