Welcome to South Yorkshire Hospital's paediatric department, a small division full of wonders and misconceptions.
Aileen Jefferson is your cold, sarcastic surgeon whose heart works a little too differently from her mind. Ever since she encountered a dangerous car accident that turned her traumatised, she has decided that it is time to shut her loved ones out of her life.
Without a notice, this attracts Niall Horan, your Greek God-resembling surgeon who just got transferred from a hospital in Ireland. By the moment he lays his eyes on Aileen, he comes to a realisation that she is truly one of a kind. With his never-ending curiosity and happy-go-lucky charms, he is more than determined to crack her shells open.
As two surgeons with their own stories cross paths over a not-so-endearing fate, what will possibly happen when Aileen and Niall begin to unravel each other's secrets?
