KSBKBT is going Kkusum way. When Kkusum left the house before the leap and was going to Ludhiana and the train met with an accident evevrybody thought she died and she came after 18 years whe n her daughter Kumud came to Mumbai and was working with kapoors (her father).
So now I guess Tulsi will come into picture in front of Virani's when her adopted daughter will come to mumbai and fell in love or in trouble with junior virani.
