Ok.. the most obvious ways are:
- Heer being busy at work and not having enough time for Prem
- Heer being more successful in office then Prem and Prem being all jelous.. (i don't think this can be the case.. Prem loves Heer too much, he can't be jelous of her heer)
What else??
At least.. they are together! I am only watching the show until they are together.. the day something huge happens! Bye kis desh mein...!!
