I have complaints about him how he treat Abhira.But he shouldn't be nice to her just because Abhinav treat him nicely.We don't ask this to siblings whose both parents are common . Because for Abhir, Abhinav abhi bhi uska papa hain,not step.thatswhy he always looks at his family picture with Abhin and Ak.So he loves Abhinav and considers him his own,it's not gratefulness for raising him up even after not being son.According to him uske mamma papa uska hain ,he dint consider them as Abhira's .
Anyway it's all not a reason to behave with her rudely.Time needed for developing Sister brother bond .He still can be considerate towards her.Can find out the truth in a neutral way.he don't do all these things
