This love triangle thing was so obvious in today's episode. Rishabh is cleary head over heels for Mandana. He openly told that since he entered the house, he was taking baby steps to come close to Mandana but she was not responding. Now she is friendly but no matter what she will do, he will always be her friend. Not only this, the excited way he was talking all this, his body language was clearly telling that he is mad for her. On the other hand Mandana was cool, laughing at his enthusiasm and giving a friendly smile but the way she said that I love you too stupid was as if she likes him too but as yet only as a friend.
As for Diggy, she seems to be yearnig to get some attention from Rishabh and is jealous of Mandana but he treat her only as some young girl to whom he wish good luck as an elder. He is clearly not interested in her. Even the way he was sitting today was telling a lot. On his one side it was Diggy and on the other side it was Mandana. And all the time his face was towards Mandana and he kept his back towards Diggy.
