What A Hundred Billion Heartbeat is about
Terminally ill Aria signs a one-hundred-million-dollar ‘surrogacy’ contract with cold tycoon Julian to fund her revenge. As they test each other, feelings grow. At the tycoon’s gala, she outshines everyone with her wits and sends her abusive stepfather and birth mother to prison. When her heart failure worsens, Julian spends billions to force a heart transplant and save her.
A Hundred Billion Heartbeat is a 70-episode vertical short drama from MicroDrama, built around revenge, CEO romance and marriage drama.
Is it worth watching?
Watch it for 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.
The whole series takes roughly 1–3 hours, so it's an easy binge.
