Fierce Grace: Braving the Betrayal

For the sake of her boyfriend, Kyle Jensen, Myla Young sacrifices her studies and pursues a career abroad.

Secretly supporting Kyle's education, she ensures his success, even securing him a position at Foster Corp in Osian.

DramaBox released it as 106 bite-size episodes mixing revenge, billionaire and secret identity, made to watch on a phone in one sitting or a few.

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 2–4 hours in total, it's quicker to finish than most full-length series.
