Take Care of My Cat - Wikipedia

Five girls in the South Korean port city of Incheon graduate from high school and struggle to keep their friendship alive, even as adulthood forces them down separate paths. Hae-Jo (Ji-young Ok) takes a job in the financial world, while Ji-young becomes withdrawn following a family tragedy. Twin sisters are satisfied peddling junk jewelry on the street. And despite the best efforts of Tae-hee (Bae Doo-na) to keep everyone together, the girls become increasingly distant.
