Crash Landing on You Quiz

Everything about the cast of the tvN romantic drama that ran from December 2019 to February 2020 and became a worldwide hit on Netflix. The set covers the 28 billed performers: the four leads and the recurring supporting company, not the guest and cameo appearances. Names are written Korean style with the family name first, and the type-in also accepts the Western order, spaced and unhyphenated spellings, and the common alternate romanizations, so family-name-first, given-name-first and joined spellings all count. The answer is always the actor, never the character. Cast order and roles come from the show's billing, corroborated against Wikidata and the Wikipedia cast table.
