Everybody wants to know the secret to lasting love. The new Netflix docuseries My Love might just hold the key — and EW has an exclusive look at the first trailer.

Expanded from Korean director Jin Moyoung’s celebrated documentary My Love, Don’t Cross That River, the series follows six couples around the world over the course of a year. Hailing from Korea, Brazil, Japan, India, Spain, and the U.S., the couples have been together anywhere from 42 to 60 years and share their stories, as well as the foundations of their long-lasting relationships.

Each of the couples were followed by a local filmmaker, and the trailer showcases the tenderness, care, and humor that makes their love thrive.

My Love hits Netflix April 13.
