Riddhima, you said to Sid that "Tumhe pata hain Sid, tumaari honesty mujhe sabsey zyada acchi laagti hain. Tumne mujhse kabhi kuch nahin chupati."
You have also said, "Aagar Armaan hota toh kabhi nahin batata." I can't get from which angle do you think that Armaan can hide things from you.
If you research then you will come to know that Sid has hidden something from you. And that is, his first crush TAMANNA. And neither he hasn't ever mention to Riddhima about her.
Then Riddhima how can you say to him that, "Tumne mujhse kabhi kuch nahin chupati."
So we can now see how honest he is.😉
