Mumbai: Actress Hina Khan, who became popular through her role of Akshara in TV show "Yeh Rishta Kya Kehlata Hai", is helping her on-screen husband and actor Vishal Singh to understand his character. Vishal, who recently joined the show as Naitik, has praised Hina for helping him. The duo, who have returned from the Switzerland schedule of the show, shot for some romantic moments there. "Hina is an extremely warm person. She was very cooperative and she even gave me insights on how to be during the scenes with Akshara and Naitik," Vishal said in a statement. "We exchanged a lot of tips and valuable nuances about Naitik's character. It didn't feel like I was shooting with this team for the first time. It felt like home," he added. Sharing his experience of shooting in Switzerland for the Star Plus show, Vishal said: "Shooting in Switzerland was a surreal experience. Having said that, the entire cast was extremely warm and I was welcomed very well on board. I had a blast with the team."
