@OP Yes it exists , but it is unconditional , it does not demand love in return , it believes in just giving , not in give and take. When do feel it ? When you :
- Are sleepless at nights and miserable in day time ( Na raat ko neend na din ko qarar)
- When you see that who you love Dill zor zor say dharakta hay , sans teezee say chaltee hay.
- Graibaan phar k sahra main nikal janay ko jee karta hay.
And there are many more symptoms , you will know them all when you are infected with love bug. Wait for your turn.
