No idea yet what fortune he has. Printing factory / business can be big, but is that all? Land, farms, shops/Mall, anything from his music based past?
Dont think we will get any details unless they create a situation that involves one of these - suddenly we may hear there is fire in his farm, which Radha will douse somehow. Well... we will then know he has a huge farmland.
They need to get into some details about the back story rather than creating situations after situations. Tulsi died, but why did she leave home - mom and D? or just mom? or just D? or D with D's mom?
Engagement, havan for the ghost, G kidnapping, Gita Drama, Tulsi drama, school competition, among other small ones ... what next?
