Avantika was the second wife rite since Karthik is older than Angad. Naina and Dilip were married before and came to Mumbai. Then Dilip pretended to love Avantika and married her and then killed himself or rather pretended. Nobody knows he got married again. Avantika went to jail. Dilip and naina raised Angad and took the money.
Do I have the story rite?
