The cast was revealed this week, with Bonnie among the main characters.
She will star alongside Peaky Blinders actor Jack Rowan, Masali Baduza, The End of the F**king World star Josh Dylan, Kiki Brimah and Peep Show's Paterson Joseph.
Bonnie took to social media shortly after the announcement to share her excitement.
“'For all the things we might have had and all the things we’re never going to have' ... Love is never black and white,” she wrote, teasing the series.
A trailer, released late last week, shows Bonnie as part of a group hugging another character.
