Yes she should ask her.
Yaar jab dimag main canons bante hain na aisa hi hota hai, Mishti misjudged Ruhaan first which was wrong and her behaviour with him was an eyesore to watch but when she got to see his true side she was the first one to confess feelings. Till then did she listen to anybody? Veer said Ruhaan was not wrong, Pari supported him, did she listen to them?
Achha the scenarios are different..After getting to know the truth she herself went to him and apologized ..Here Pari came to know the truth still in denial mode..There is lot of difference..Anyways I don't want to comment more abt Pari..Cool😊
