I think its Prithvi. Despite the fact that she left him at the altar twice.. i mean in the very beginning right before engagement and then later on when misunderstandings were cleared with Angad right before her marriage to Prithvi, he didnt directly torcher her. Yes, he did kill Josh and all that but unlike Angad he didnt torcher her in marriage that you left me blah blah.. Also, he even comitted murder for her.. Angad would never do that lol. Not that it was the right thing to do but hey it shows the extent to which this man loves her... i think PRITHVI definitely loves Kripa more and also unconditionally than Angad...
thats my opinion!
