6 months Marriage Deal

My first ever post and it happens to be a doubt😆
How will a 6 month marriage deal solve Arnav's problem?
His sister is preggers yes! But it takes 9 months for the baby and considering everything else will 6 months be enough?(Could be a possibility though)
Will Shyam turn into a saint in 6 months? what guarentee that he wont leave Anjali in 6 months? Also, when he has tried killing Anjali so many times.. why wont he kill her in the next 6 months? Ok so Aranav doesnt know about his attempts.. but wont he again get into the "want to marry Khushi" mode after 6 months? Aranav runs a business ... seeing the long-term gains and loses should be like reflex action to him... why does he think only 6 months is gonna solve the problem?
I simply fail to understand what will a 6months timeline achieve to solve any of Arnav's current problems. Anyone got any clues? Sorry if there were posts made about this since morning... if yes, could anyone direct me to that thread... would like to know what the junta thinks about 6 months solution to Arnav's problem

i don't think anyone has the reason for why it's 6 months..as we know this part was dubbed anyway..so probably a last min thing? but yes the 6 months thing doesn't add up..if it was 9 months then yea it would be for anjali, but 6? :S why not 4, 7 or 8?
