Armaan because Karan honestly seems like a big time flirt. I don't see anything wrong in that, but the guy's got a girlfriend. He should at least respect that fact and not flirt with other girls. Plus from all of the articles that I've read about him, I really think he has a narrow minded view on girls. No offense to anyone. He also says that the first thing he can't wait to do when he gets to a party is get drunk. I really hate drinkers. His character is honestly much more sweeter. I mean the whole Karva Chauth ka vrath, covering for her dad,standing in the rain, car accident, millions of sorrys, caring so much for the kids and patients and staff. He's the perfect guy! So my choice is definitely Armaan!
