Is it her way to give him a reminder?

Ok we all know Sai gets jealous whenever she devar bhabi maa together bcoz she already started feeling for her deal wala husband

Why she always brings Pakhi in their conversation?

Is it her way to give him a reminder that you promised Pakhi that no one will come in your DIL ?

Am i thinking too much ?

She wants to know what Virat feels for Pakhi. Even though he tells Sai that Pakhi is his friend, Sai is need of assurance because Virat hasn't explicitly drawn a boundary and Pakhi is always behind Virat. It makes Sai frustrated.

sai knows that they are more than friends, so whenever virat tries to give her husband waala vibes she reminds him of pakhi. and tells him that their marriage is a deal. its more like reminding him that

'aap mere saath lovey-dovey baathein kar rahe hai aur upar se aapki ek ishq waala best friend bhi hai jo aapkeliye khana laati hai, paani leke khade rehti hai, care karthi hai, so spare me am not your real wife but a deal and zimmedaari waali wife aapko jo bhi chahiye apni bestfriend ko boliye, waise bhi muj par aap humesha chillate hi rehte hai aur apne best friend ke haaton mein baraf laagaate hai woh bhi muji se mangwaakar, i dont care, main tho apne doctor ki padai karke nikhal jaaongi, aap apna dekhlo'🤣🤣
