jai, roshni and bani's mum went to same college..so they all knew each other...may b jai n bani mum had an affir in old days but after she got married to nishkant..
jai moved on with his life and fell in love with roshni...n roshni got pregnant...
however, bani mum realised her mistake as nishikant had bad habits n she was sufferin with him,so she decided to go bak to jai. roshni must have lit fire in the house on park road(same the way bani was caught in fire)...
ND rosh tells jai .....jai run to rescue her n they go to the same hospital...nd doctors(the one who recognised jai in the hosp) fail to save her life...so she died...
nishikant blakmailed jai n rosh,who promised to give him money for gambling n stuff n also to look after their daughters,which jai did really WELL 🤔
I HAVE LOST THE TRACK...........
SORRY IF GOT BORED N CONFUSED...
THE BEST THING TO DO IS...WAIT N WATCH..............lol
