Sidhi to make him accept his love should try out reverse psycology, should start wearing more of blue sarees and kurtis (which kunal hates), talk more about Anand, how her life was with him, more often mention his name in front of Kunal, prepare dishes which Anand likes, take Kunal to the coffee shop where they used to spend time , in bedroom also just irritate him by doing something related to Anand , do things which Kunal does not like, stop caring about him so much, stop running to him whenever he calls her or responding to what ever he says.
May be by doing this one fine day our angry young man would erupt like a volcano and all his feelings would come out and with that the confession .
