Since I'm not familiar with this particular 'intezaar sad love story', if you could share some key details about it, like the main characters, the setting, or the basic plotline, then I would be able to give a proper summary.

It could also be a story full of jealousy and longing as the person watches their beloved be with others.
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.
