Actress Soha Ali Khan, who has guarded her relationship with Kunal Khemu well so far, made a candid confession by saying that she feels reluctant to accept her mistakes, and say 'sorry', while Kunal feels possessiveness in every relationship is important.

"I am very proud and find it extremely difficult to say the word 'sorry'. I usually end up arguing a lot in the bargain," Soha said while playing peacemaker between a couple for an upcoming episode of UTV Stars' "Superstar Santa".
