i feel that day balloon symbolised everybody related to mishbir
it shown that in the process of their love noone will help by ballloon bursting one by one
and the three balloon which was left symbolised only three people will help them to make udaan of their love
first bp bm no need to mention they by giving their ashirbad and third will be baba who will help in marriage but after that although they will not stop supporting him but they will neither help mishbir to fly more high they have to go high with themselves together with their love
although still i dont like mishti character or even abir somewhat in term of mahanta and sacrifices
but to kuku fans who blames mishbir for their misery i feel they themselves r responsible for what they r today kuhu was the one who always called for help ya she many time ask mishti not to interferre but then she ask for help when thing goes south she never seen kunal real face but he shown her if mishbir helped her to be with kunal thenit was her responsibility to even tell abir when kunal put forth demand of separating mishbir but very conveniently when she need help she call them but when she theink she not need she just remove them as fly from tea so mishbir r not responsible for kuhu getting betrayed by kunalbecause he was on separate mishbir mission but kuhu even knew if she 1 time would be right she would have honestly told mishbir the truth and would not be here where she is
mishbir fans blame kuku but i feel both couple r there to create drma in each other life like today abir told if two people want to be together they will be no matter what so that is only the case bith couple create drama and situation in each other lives but when it come to solve it they r showing the difference
anyway i feel all four r responsible for all problem in each other lives one is doing deliberately with selfish motive other undeliberately with selfless motive
now some fans will blame abir when kunal will tomorrow will heartbroken he will just agin do blame game but if u remember mishti on sangeet day even same happen but she was not angry or heartbroken even though he deliberately done this andmeenu cruely shown the video so its upto people how they act and kuku and mishbir just reponsible for their own misery for what they r not anyone else
