Let me try to sum up the possibilities
a. Meenu double crossed Mishti and Abir decided to take Mish's side and leave Meenu and the house
b. Abir learns of Mehul's truth and is heartbroken and Kunal is consoling him. Though from the picture it looks more like Abir consoling Kunal to me
c. Kunal being Mehul and Parul's son is out in the open and Kunal is heartbroken. Abir is consoling him...
d. Abir breaks up with Mishti as per the spoilers and RVs are consoling Abir. Though DKP post says paths may change but love remains under the brothers picture so the issue is between brothers and not MishBir
e. Abir is fed-up of everything after learning of Baba's truth, Meenu hiding things all her life and Mish's jasoosi and decides to leave the house and live a banjara life
This is all I could think of... Add your own if you can think of more
