Guess you're yet to catch up with all the episodes. Ronakshi faked being in love at one point before Rohit actually fell in love with her. And after Raima's return, he told his family that they were faking it (though by the time he made the declaration, he had confessed his true feelings to Sonakshi).
Thank you for replying. I am currently on save dr sippy from tree episode. Actually curiosity jab tak satisfy na ho..i can't continue watching.. so when did he finally tell about (Rohit Sona) them truly falling in love with each other to family..?
