I decided to get married underwater so that people would understand that we should not pollute any natural resource," said the software engineer based out of Chennai. However, it was his wife's first time in the ocean. "I didn't know how to dive, and I was initially very scared at the idea. But we took lessons for three days, and I overcame my fear. I'm happy at how things turned out," said Shwetha, who also works as a software engineer.
