trupti and veidehi

guys i think that veidehi is trupti's real daughter. i mean trupti is a type of women who does not care so much about other ppl, and for her to care for some headmaster's daughter, i doubt it. i think its her child with rishab. when she was pregnant, her and rishab planned to get virani's wealth with trupti sedcing sahil and marrying him. so when she gave birth to veidehi she prolly gave the headmaster some money to take care of veidehi or the headmaster was childless and decided to keep vaidehi. if trupti kept veidehi, she would not be able to marry sahil. wat do u think guys?
