Already gave you guys the answer but you are discarding it as it is ITVđ¤Ł
On a more serious note, go back to the ep where Katha speaks about the rooh of the project. Got Viaan's attention from there on. But the problem with Viaan is that he is a control freak and does not give much away. We just see him being intrigued by Katha but we never considered that he was attracted to her. But now, they are showing us the hints of this attraction. Yesterday's ep was a turning point for it showed us that the sparks are on both sides, and both are fighting it in their own way. Neither can accept the fact that there is something there. But Viaan is a different ML. He paid to go to the next levelđ¤Łinstead of analysing his own actions, he is trying to understand Katha's perspective. The guy is hilarious in his complexities.
Few months down the line, all of us will fall in love with Viaanđ¤Ł
Did katha showed interest in him?? In which scene?? I couldn't figure out.. I only saw him being interested in her and her giving him deadly glare..
