If you loved Lost in Love, try Late Blossom
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Choo Chang-min, and they both carry the bittersweet, tender mood tags, and they sit in Drama / Romance territory. If that's the register that drew you to Lost in Love, the second film will land in a comparable space — through a different lens.

What Late Blossom is
Love is in the neighborhood, apparently. Two couples live parallel lives, crossing paths occasionally. It's a quiet look at ordinary lives.
