Girls season 4 returns in a month on HBO and fans can't wait to learn more about their favourite couple Hannah and Adam.

In the season 3 finale, Adam lashes out at Hannah for diverting his attention towards her Iowa plan before his Broadway performance as he thinks he's missed it again.

This has left many fans speculating about their future as Adam seems more leaned towards Jessa.

"The plan is... there is no plan," is the latest approach of Adam Driver's character towards Hannah's move to Iowa for the prestigious writers' workshop.

The caption of the official poster of the series reads: Prestigious writers' workshop "nowhere to grow but up."

Hollywood Take suspects that season 4 will be all about the girls becoming more mature and learning new things.

According to the show's promo, Hannah will find herself in a whole new environment while still struggling to manage her relationship with Adam.

Slash Film suspects that Adam might end up hooking up with Jessa (Jemima Kirke).

His sister Caroline has described him this way to the budding writer: "You know Adam, he really is at his best when he's nurturing the poor, the lost, the profoundly damaged" — and the website suspects Jessa fits that description much better than Hannah.

It will be interesting to see how the girls' lives will move forward in the Lena Dunham created series.

Girls season 4 premieres January 11 on HBO.
