arnav came back because he loves khushi but part of the reason of his return is that whole khushi/shyam track.
what happened to garima 14 years ago happened to khushi 14 years after.
all happened for reason for arnav to see that his dad was to blame and i think if he did not see what khushi had to go through he would not of easily of forgiven garima and moved on. if you guys get what i mean. i can't explain itðŸ˜
