Is your tea okay? I am very fussy about my cup, so I ask everyone," asks Naina Bachchan. We are sitting with the investment banker and her husband, actor Kunal Kapoor, at their Juhu home on Thursday evening. Naina is back from her Worli office, and is casually dressed in white sneakers, jeans and a tee, while Kunal is lounging in a white tee, pants and a beret. We sit in a room with two defining characteristics -- shelves full of books (arranged according to subjects like yoga, meditation and non-fiction) and a piano. "I think both of us have different ratios of creative and business acumen in our lives," says Naina, as if explaining how people who could be thought of as different as the two of them, can be together. She is right. Kunal, the creative one, is behind successful fundraising platform Ketto, and Naina, the business brain, is a trained pianist.
