In 2026, Oliver Smith emigrates from the United States to Austria to start a job. Anxious, tired and broken, he hallucinates an angel comforting him on the plane. Ollie assumes it was a dream, but the lawyer Moritz who picks him up at the airport assures him that angels are real. As Ollie builds a new life on the other side of the world, working his job while trying to keep himself together and hold his shadows at bay, he meets Bryn, a young man who practices a secret magic and sings gentle prayers to the sunset.

In 2027, one year since emigrating from the United States to Austria, Ollie has settled into a happy life in Vienna with his two boyfriends, Moritz and Bryn.

The Schöner Himmel coffee shop is forced to close, and with the mandatory ambulance service and the military deployed, Bryn and Moritz are called up.

Come what may, I have what it takes to hold us together. Two years after the events of Nebulae, Bryn, Moritz, and Ollie are enjoying peaceful days and continuing to build on their relationship.

Bryn never thought he'd become a parent or even an uncle, but seeing everyone around him so happy at the prospect of children, he is doing his best to open his heart to the fruitful gifts that life can bestow.

Tired of shallow hookups that went nowhere, and wanting something real, they turn to their friend Florian for advice.
