What Whose Nanny Is a Stock Market Guru? is about
A legendary Wall Street investor returns home under a fake identity to find the lover and daughter he lost five years ago. When she mistakes him for an applicant, he takes the job as their nanny to quietly protect them. As ruthless corporate rivals threaten to destroy her business, he secretly uses his financial genius to fight back. But how long can he hide his true identity while shielding his family from ruin?
It runs 65 short episodes on iDrama and leans on CEO romance, billionaire and marriage drama tropes, with each episode ending on a hook.
Is it worth watching?
The draw here is the power gap between the leads and who ends up holding the cards. On top of that: the hidden-wealth reveals and the people who misjudged the lead.
Plan on roughly 1–2 hours from the first episode to the finale.
