Meet Me on the Buddy Bench

As a primary school teacher, Ava Lam is familiar with the 'buddy bench': a rainbow painted bench where sad or lonely children can sit to show they need a friend.
But are buddy benches just for kids? Ava might have assumed so – until she finds herself sobbing her heart out on a park bench and a kind stranger sits down next to her.
The stranger, Dr Sam Stone, has a house, an impressive job and he's even training for a marathon – all things that have become painfully out of reach for Ava in her new and scary circumstances. But whilst Sam appears to have everything figured out, it seems he needs a sympathetic ear just as much as she does.
Is the encounter a one-off, or could the 'buddy bench' begin to represent a source of comfort and support that will become precious to them both?
