“Better Late Than Single” is Netflix’s newest dating obsession, and fans are already hooked on the glow-ups, the mentor chemistry, and the surprisingly honest confessions. The twist? Contestants don’t know each other’s ages or jobs at first, and they only get the reveal after leveling up their confidence (and flirting) with help from four celeb mentors: Seo In Guk, Kang Han Na, Lee Eun Ji, and Car, the Garden.
Netizens did their homework, we did ours, so here’s your clean cheat sheet to every contestant: ages, occupations, and Instagram handles in one place. Scroll, follow, and tell us who you’re rooting for.
