I think angad should forgive kripa because
If kripa was able to forgive angad after he found out the truth the first time they separated that it was all nania and kartiks fault, and that they forced him to almost marry mishty, and leave a pregnant kripa claming that it's not his baby, and that she slept around
He should forgive her for this little mishap
All she did was support her friend, and there was strong evidence against poor angad at that time,
So he should forgive her, he had made a bigger mistake than her
