They r protecting piya. But why?

They r protecting piya from abhay but y? They even dnt know that abhay is vampire so why all these protecting drama? Neither misha nor panchi thought to ask abhay that y the hell we need 2 protect our sister from u? They want pia to b with jay but y with jay and nt with abhay? Why they r forcing her to b with their choice. Pia lost her memory but they dnt know its abhay who erased it. On that night whatever happened with pia was due to maithily and sid, they even dnt know abhay was in jungle, so why this protection act? I agree that before the leap piya has gone through heart break so many time coz of abhay but in clg lyf all these things happens, just to save pia from one more heart break entire dobriyal family getting engaged with abhay. I think they should leave pia alone and let her do whatever she wants rather than making her lyf more complicated. First mish misha and now panchi... They think they r protecting her but actualy they r killing her slowly. But still question is why they need 2 protect piya? And i think they should get it clear why we r doing this melodrama before starting it?
