After tonight's dance.
I feel Reyaansh somehow started trusting Kria atleast a little because inspite of her injury she danced with him without ditching him.
I highly doubt if Reyaansh is suspecting Kria's behaviour now.
Kria once said she had a reason to leave him before but he wasn't ready to listen to her.
After this I feel,
He is giving a benefit of doubt to what Kria said was true that she had a reason to leave him n left.
Reyaansh's monologue is so much needed in the situation to clear up things.
Moreover,
I felt he was happy for the prank becoz he was proved wrong that Kria would ditch him for the second time.
MONOLOGUE HIGHLY NEEDED Asap.
