I think u are right ,you are bringing back my lost interest 😂
In one of the BTS Aditi mentioned ki Katha finds out something which makes her think Vian cant do this
Viaan might reply to Katha in car while going to pitch meeting, that he will message her dhaba details for dinner therapy session or can say its a surprise.
In message that Shamita showcases as proof in office after her grave allegations on Viaan, there might be mention from Viaan to her 'meet me tonight'.
Now if Viaan is going on dinner with Katha same evening, Katha might have doubts why will he then demand ONS for same night at a different location with Shamita in an SMS?🤪 that too when he already expressed in Lonovala how guilty he was & feeling so wrong in judging women due to his childhood trauma?
