Yeah without Jassi Armaan is lost. He doesn't know what to do. He needs his jassi.
Or
Armaan is trying to look ugly to make Jassi feel good (but still he will look adorable to me, no matter what).
Or
Purab kidnapped Armaan's barber.............b/c he doesn't want Armaan to get a hirecut b/c he looks ever more cute/handsome after the haircut and Purab is afraid that when Jassi comes back...........she would go back to Armaan b/c he looks cute/handsome.
Or
Armaan wants to grow long hair so he can donate them and they would make a wig like Jassi's old hair
Or
He's missing is Heer too much and can't think of anything else but his heer.
Well said.. I think thats the reason for his avatar...
