HBO is bringing Togetherness back for a second season. The pay-cable network announced Tuesday that it's renewed Mark and Jay Duplass' freshman comedy for another season in 2016.

“We began our love affair with HBO in our parents’ living room in 1983," said the pair in a joint statement, "and to have these brilliant, creative people put a ring on our fingers with a second season of Togetherness is a real-life dream come true.”

Starring Melanie Lynskey, Amanda Peet, Steve Zissis and Mark, the half-hour show has been a passion project for the busy brothers since they first started developing it at the network two years ago. The pair wrote and directed each of the first season's 10 episodes. That's on top of their other TV duties — Mark stars in FXX's The League, and Jay stars in Amazon Studios' Transparent.

Full ratings for the comedy, airing Sunday nights between returning comedies Girls and Looking, aren't yet available, as HBO is now reporting gross numbers after live-plus-7 stats are available. Preliminary data has it pulling 2.6 million viewers per episode, prior to additional, time-shifting lifts.

The second season will tape in Los Angeles later in 2015. And the Duplasses will have to squeeze that into their increasingly busy schedules. The brothers and indie-film veterans just made a four-feature pact with Netflix at Sundance.

That said, they've also been quite open about having the television bug. "I want to be on set with Jay making our television show for HBO," Mark told The Hollywood Reporter in December. "I don't want to be on a $6 million independent-film set where they're freaking out about whether they're going to get their money back, and they're beating the shit out of us all the time."
