Which CORTIS names and lines belong on a fan card?
Here's a detail we keep seeing when we run fan messages in 28 languages: everyone reaches for 오빠 (oppa, "older brother") by default. But CORTIS only debuted in August 2025, and the members were born between 2005 and 2009, so for many fans that honorific doesn't actually fit. For a rookie group this young, most fans just write the bare stage name — 마틴 화이팅 (Martin, hwaiting!) — or add the neutral 님. You don't need a sibling word to sound warm.
A CORTIS fan card has very little room, so every line has to earn its place. The strongest thing you can write is the member's name in Hangul plus one honest, specific line. CORTIS is BIGHIT MUSIC's "creator crew" — the label's third group after BTS and TXT — and their fandom is COER (코어). Below is a line for each of the five members, then six song phrases from their debut EP Color Outside the Lines that any COER will recognize.
Which CORTIS member's name should you write first?
Pick your bias and copy the line. Each line uses the member's stage name in Hangul — no honorific needed.
