wen did onu and nupur meet?

in today's episode, nupur said that six years ago they both met but onu was sent abroad eight years ago?????

I so want to know how he fall for her ... i mean they did hint at it in friday's epi but i seriously want to know how he fell in "love" with her ... but i think BT will leave it to our imagination 😡 or may be not may be they will reveal it when they show Onu going mad 😆

onu had told taani that he used to feel jealous of nupur in the beginning and after 2 yrs wen he started to forget taani and became frnd of nupur they fell in love...........
but they had met earlier. i mean this can't be possible that for 2 yrs nupur had been hiding herself from onu in her house only..........
really dats very much confusing. so let's not use our maths here and njoy the show🤣
