Sealed in Concrete: The Heiress’s Revenge

Sealed in Concrete: The Heiress’s Revenge belongs to the new wave of vertical dramas: a revenge and rebirth & time travel story framed tall and cut into bite-size episodes. With 35 episodes lasting a minute or two, the whole story takes around 53 min to watch from start to finish. The plot, in short:

Wheelchair-bound heiress Chloe was drugged and left to die by the man she loved. Then she got a second chance. While her fiancé still sees her as his helpless victim, Chloe gets away with a perfect crime—she seals his family inside the basement with concrete and fools him to bury them for money. This time, she's not the one begging for mercy.
