Yeah piya has right to move on wid jeh or any other guy but in my view abhay raichand situation is more difficult then her & pia is in this situation then only its her self to be blame for it.
My explanation
Since start she always tried to stalk him due to her curiosity, abhay tried very hard to be rude so she can stay way from him though he also loved her so much. Ultimately she knew truth about him then questioned him for why he loved her as he is not human, c'mon poor girl its you who first stalked him, made him get attracted with you. then after wards new problem came with sid n ultimately abhay had to propose her & make a fake relationship ( feelings were real) with her so she can divert from her new curiosity to know about sid & but she never learn t lesson & never trusted abhay ultimately almost got killed by sid , but again abhay safe her, abhay loves pia but logically he always know their relation never possible but for pia he became obsession. he had to erase her memory with out her permission but it was essential to live normal life so she can not be in danger to know about super naturals exists. now in season 2 Abhay still wants her happiness & wants to stay away from her but destiny forced him to go once again in front of her, He tried every insulting trick to make her move on with jeh but one fine day he came to know jeh is not the right guy so situation became worst for abhay as neither he can tell the truth or get her memory back nor pia will be convinced after such a bad treatment he gave earlier on.
So Abhay raichand always in difficult situation then any other cast of this show.
Still pia can move on with happiness but Abhay raichand can't .
Pretending a bad guy & doing good things is always tougher then pretending a good guy & doing bad things. Abhay Raichand the hero of PKYEK 😃
