so u all noticed today episode spoiler

the invitation letter was from bhuj 

bhuj is related to his father as it was mentioned in some episode where meenu got to know abir detetivegiri for his father

so basically abir left his father even whom he loves the most and is most important to him just on mishti asking him in drem only

Yeaaah.

So my guess was correct.I paused my screen to find out about the invitation but it looked still hazy.

I thought mayb he was trying to find clue about  his father.

I was thinking right.

Love the way yrhpk never leave any loopholes. 

From time to time,they keep mentioning Abir's dad.       

He is never totally out of Picture.
