The One and Only (Season 1)

The One and Only (한 사람만, 2021) is a South Korean drama series you can watch online on iFILM. Pyo In-suk has always felt she doesn't belong — and finding out she's terminally ill barely shifts that. Then a stranger appears.

The premise is genuinely unusual: a contract killer, a police lieutenant and three dying women who have each decided to take one person's life before their own ends. An Eun-jin carries the lead with precision; Joy from K-pop group Red Velvet and Kim Kyung-nam round out the ensemble. Director Oh Hyun-jong keeps the tone spare — no tidy resolutions, no comfort handed out to the audience. Stream The One and Only online on iFILM.
