Fine.
Four letters. One word. A million different meanings. After a traumatic work accident that left a colleague dead, Yoo Ayeon is back at the 32nd precinct and falling into tired routines. She tells everyone she's fine, she shoves her emotions into a vault built from a childhood of fear, and she pretends that nothing can make her feel. When she's called to a flower shop, Ayeon meets the owner, Jung Jaehyun, a man of mystery dressed in soft colours, calming smiles, and fragrant roses. As she's thrust into the orbit of someone so much unlike herself it becomes a lot harder pretending that there's nothing beating in her chest.
