hmmm...In my own opinion I dont think her sister would do that, I mean from the childhood case where she said
"everyone would always leave us, they would never come back"
she was obvious making his brother only look at her sister and saying that Iam the only you could trust.
What is sure is that her sister is trying to take back what is originally belongs to them, because gis brorher is kund of useless and she is the type of character who would be willing to do anything, I mean her sister started acting like a Villainess since they were young but yah that was to prevent her brother to turning to a weakling
if what Iam saying is true, pretty sure there would be emotional talks after, with flashback, and how I feel stuff
I bet his sister is pretending so they could later on turn the the tables ლ(´ڡ`ლ)
