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.
I'm not sure who Ankush and Oindrila are specifically. They could be ordinary people with a personal love story known only to their friends and family. Maybe they met in a coffee shop, their eyes met across the room, and from that moment a spark was kindled. They gradually got to know each other, sharing their dreams and fears, and fell deeply in love.
I'm not sure specifically which 'Ankush Gedam' you are referring to. There could be many people with this name. More context would be needed to tell the real story.
The main plot could be that of a heartbroken student. They discover that the person they like is in love with someone else. So they have to deal with the pain of seeing their crush with another person every day at school. They might struggle to move on and find themselves constantly comparing themselves to the other person their crush loves.
There are so many possibilities. Maybe they both volunteered for the same community project. Ankush was impressed by Oindrila's dedication and passion for helping others. He introduced himself, and from there, they began to build a relationship. They might have worked side by side on the project, sharing ideas and laughter, and as time passed, their feelings for each other grew into love.
I'm sorry, I don't actually know the specific love story of Ankush Choudhary and Deepa Parab. There could be many different versions or it could be a very personal story that not many are familiar with.
