Comment by Pass on My sister, who was my enemy, loves me - Chapter 17

I'm actually betting on the sister being the one who used the regression magic. After all, the one who uses it needs the jewel and won't remember anything but what if she used it in hopes of the little one having a good family and life instead of the awful one she had? She wouldn't remember but she had in the past life opportunity to get everything and do it. And with her little one having the adult brain, she would see through things that they didn't see through as kids. And wouldn't keep running and escaping from her just because she's "scary".

Who ELSE would have the motive? EVERYONE ELSE was made to be understood to be dead. If she truly hated her, she wouldn't have bothered to ask those things in the first chapter. The first timeline, neither of them communicated properly and a lot of misunderstandings along with manipulations were afoot.

@Pass I think ur jumping to the conclusions man, we don't even know what happened in the past life. It's just said that the sister tried to assasinate her, we don't know if it was really her . Maybe someone did the same to elder sister too and told her it was fl? Or manipulate her into hating her and making her believe she did evil things? Like we don't even know the elder sister's pov , don't jump to the conclusions so quick. This show has magic too so maybe someone did black magic on her ? Until we find out ,we can't blame 

@Pass plus maybe the king was evil and maybe someone made her believe she was behind all this. Because she was confused in last timeline too why fl gave her all the info about king. I really think she was trying to hold everything together until she was made to believe something. It was like this in Who made me a princess too so I'm thinking obviously it's not the same but there was some big communication gap between them too because they were also not really close from the looks of it,they maybe never tried to got to know each other.
