His Nighttime Obsession

Heiress Lydia loses everything—family bankrupt, father dying, sister hunted. She makes a deal with Rian, Dynasty family's ruthless second son: seduce his brother Leo. It's a survival game. But Leo hides a dark secret, and Rian shows her unexpected tenderness. What begins as cold revenge becomes a trap of the heart. In the abyss, they become each other's only salvation.

It runs 50 short episodes on Reelife and leans on revenge, billionaire and secret identity tropes, with each episode ending on a hook.

The draw here is the slow build to a payback that lands hard. On top of that: the hidden-wealth reveals and the people who misjudged the lead.

At roughly 1–2 hours in total, it's quicker to finish than most full-length series.
