My point of view-both are not a dream

My imagination:

Both get off in the next stop. Siddhi was telling him about richa in detail and Kunal says stop it because he sees Richa coming. So he planned to act that he doesn't believe siddhi, in order for him to find evidence to prove his siddhi's innocence.As of his plan, he started yelling at siddhi, why is she keep on playing with his feeling? Richa , who saw this, was really happy that he didnt believe her and told siddhi to back off.
