What I Mistook My Billionaire Mother-in-Law for a Beggar is about
Dressed in simple clothes, a billionaire CEO's mother visits her family's hospital, only to be tormented by her son's arrogant fiancée. To steal a VIP room, the cruel woman destroys vital documents and crushes her life-saving pills, nearly killing her. Surviving the ordeal, the matriarch stays silent and plots her revenge.
It runs 51 short episodes on iDrama and leans on revenge, CEO romance and billionaire tropes, with each episode ending on a hook.
Is it worth watching?
The draw here is the slow build to a payback that lands hard. On top of that: the power gap between the leads and who ends up holding the cards.
At roughly 1–2 hours in total, it's quicker to finish than most full-length series.
