What to Read Next
Marcus quickly discovers that Effie is dating his friend, Samuel. This creates a difficult line Marcus doesn’t want to cross. They begin working on a project together – photographing and highlighting Black artists in London – which brings them closer. However, they must navigate their growing connection and decide if they can remain just friends.
It feels like they were always meant to be together, their initial attraction blossoming into a profound love. However, love alone won’t guarantee happiness, and their journey to find each other is full of challenges. Will they overcome these obstacles, or will they be overwhelmed by them?

The show is a sweet, personal, and very romantic story. It’s a moving look at themes of love, who we are, and finding where we fit in, all presented with genuine emotion and sincerity.
