When did Kirti start liking Krish?

To be honest, I usually skip Krish-Kirti scenes. So I guess that I missed the part where they fell in love. Was there even a plot where Kirti started to like Krish or is Kirti just using Krish to take revenge because the Pandyas hurt her mother? Please do not tell me that she is using him to try hair products. Not that I care much about them but I do not understand why this pairing exist.🥱

I hope that makers take note of the fact that these two are fully incompatible in case they are getting reviews about them. The three other couples have a certain charm but I see nothing between these two.
