I'm not really familiar with the specific 'balveer aur mehar ka love story'. It could be a unique love story perhaps set in a particular cultural or fictional context.

Since I don't have much information on this particular 'baal veer aur meher ka love story', we can assume that it follows some common tropes of a love story. Baal Veer and Meher could have a fateful encounter. Their relationship might start with a simple attraction and gradually deepen into love. There could be elements of sacrifice, where they are willing to give up something for each other. And as they face different situations, their love is either strengthened or put to the test.
Well, 'tu pyar hai kisi aur ka' implies that it's a love that is for someone else. In a school love story context, it could be about a person who has feelings for someone else in the school. Maybe it's a story of unrequited love, where the protagonist loves a classmate who doesn't feel the same way. It could also be a story full of jealousy and longing as the person watches their beloved be with others.
There are so many potential characters that could be the main one beside Amir in his love story. If it's a story set in a school, it could be his study partner. In a story set in a small town, it might be the new neighbor. Without more information, we can't be certain.
If it is a song, without listening to it or having more details about its lyrics and the context in which it was created, it's hard to give the full story. But generally, a song with such a title might be about unrequited love or a sense of self - effacement where the singer feels like they are just a thought in someone else's mind, maybe longing for that person to notice them.
