Why is Astha so angry and not accepting that sia is simran and abhis daughter?
Partially because she is jealous and also very immature. She needs to grow up and accept responsibility for her actions. She needs a good spanking. I doubt it would help. SHE IS A SPOILT BRAT.
Instead of being thankful for having a newfound sister she is feeling insecure and acting obnoxious. I think all house members should ignore her and move on.
