Anirban

Anirban means "that which cannot be extinguished", in Sanskrit and Bengali. Anirbans are very helpful, with sweet personality. They might be obsessed with sex, but they never reveal it until they get the chance to act, or make a chance themselves. They can be very romantic and imaginative, but never unrealistic at the same time. Be careful before messing with them, because the gentle fire in them may turn into a giant monster if they feel wronged or insulted.

The selfless guy with a sweet smile in the crowd will definitely be Anirban.
