ReelShort is adapting Cora Reilly's Bound by Duty as a vertical microdrama, with the series set to drop on the streaming app on August 13, according to a Deadline exclusive Deadline.

The adaptation stars Casey Schryer and Chase Mattson and falls into the dark romance genre that has become a signature draw for the platform. Bound by Duty follows Dante Cavallaro, the calculating heir to the Chicago mafia, and Valentina, a young widow who refuses to settle for another loveless marriage. In the original novel, Dante's wife died four years before the story begins, leaving him to navigate duty, grief and a new arrangement that neither party chose Cora Reilly, official site.

This is the third microdrama ReelShort has drawn from Reilly's Born In Blood Mafia Chronicles, a series comprising eight novels and an anthology. The two prior adaptations have been among the most successful book-to-vertical franchises on the platform. Bound by Honor, the first, has topped 423 million views. Bound by Love, which launched in May and continues the story of fan-favourite characters Luca and Aria, has already surpassed 70 million views Deadline; PR Newswire, May 2026.

For readers unfamiliar with the format, ReelShort — launched by Crazy Maple Studio in 2022 — streams English-language vertical dramas built for mobile phones. Each season runs 70 to 80 episodes, with every instalment lasting one to two minutes. Some episodes are free; the rest sit behind a subscription or pay-per-view model Deadline. Think of it as a soap opera compressed into bite-sized, portrait-mode clips designed to be watched one-handed on a commute.

The Born In Blood Mafia Chronicles has a dedicated following that predates the screen adaptations. Reilly's official reading order recommends starting with Bound by Honor and the Luca Vitiello novella before reading through to Bound by Love Cora Reilly, official site. Bound by Duty itself is Book #2 in the series, originally published on February 10, 2015, and the series has since been collected in print anthologies and translated into other languages, including a Portuguese edition titled Ligados Pelo Dever Cora Reilly, official site.

What makes the August 13 launch worth watching is the track record. Two adaptations in, the Born In Blood franchise has collectively drawn close to half a billion views on ReelShort. A third entry, centred on a widowed mafia heir and a woman pushing back against an arranged marriage, gives the platform another entry in a formula that is clearly working — short episodes, high emotional stakes, and stories people already love on the page.
