True, it's rare to see manhwas where the relationship between sisters isn't toxic but in this case it's not toxic so it's cool
!!!SPOILERS!!
Not a major spoiler but she realy loves ancia and after the bal thei father will let her play with her so she can spy on her and tell him and when she doesn't want to he beats her, over and over until ancia finds out and saes her from him .... Voilaaa
Sorry but I’ve read too many stories where the sister seems nice at first but the betrays the mc. Hoping this sister is actually nice and not just pretending to be. My first thought when she gave her the warm crystal was that she was gonna frame her for stealing and use the handkerchief as evidence.
