Sunil Kumari was the oveprotective brother of Shanti Kumari. He disapproved of her relationship with Scotty and was often seen trying to convince her to instead date their childhood friend Dinesh Jivani. He shared a brief romance with Libby Jeffries and also dated Scotty's sister Rebecca Scott. The two broke up and nearly reconciled before Sunil learned that Rebecca was a prostitute.

Sunil attended Shanti's funeral, and in 2010 gave Scotty and Tracey his blessing (off screen) when they got engaged.
