Someday(2006)

Someday is a South Korean series that weaves together four lives through the lens of love. Hana Yamaguchi, a Japanese cartoonist raised by her grandmother, has always dismissed love as mere biology—until she witnesses an unexpected 60-year romance between her neighbour and an elderly street sweeper. Determined to understand this connection, she travels to Korea to trace her neighbour's steps. There she meets Go Jin Pyo, a doctor and devoted fan of her comics who believes he's falling in love for the first time. Jin Pyo enlists private investigator Lee Seok Man, a guilt-ridden survivor of a tragic accident that claimed his family, to help with Hana's search. Meanwhile, animation producer Hye Young, Jin Pyo's longtime friend, discovers her own feelings when Hana enters their circle. As these four navigate loss, longing, and connection, each confronts what love truly means.
