I think that an ASR and La engagement is unlikely because his character has already stated he is against marriage. And engagements usually lead to marriage. Unless something radical happens to make ASR want to be engaged to La. An X factor. Either way I think La should stay on because she creates so much friction between the leads which makes it fun to watch.
Or we could just see La simply return to the RM. Which means Khushi could continue her ridiculous job and that would also create more conflict between her and ASR. Either way La creates some sort of unpredictability on an otherwise predictable story line.
