At the starting of the serial Archu was shown as the girl who had to stop her education due to her mother's illness. sulochana was shown as the active lady , so she why wasn't sent back to school after she recovered.
Why was Manju entrusted with going to Manav's house before finalizing the alliance .All these twists and turns ensures the longevity of the show.
sulochana was never my favorite character . now coming back to the point she was shown very progressive , when she slapped Manav and got her daughter back home.so why is she insisting on getting Archu married to Jaywant . Maybe Archu's actions are forcing her to think that way. she has become self destructive , sulochana is hoping that martial bliss may cure her.
