10-second answer
The short answer
In Korea, relationship-and-age-based titles do so much of the work that a personal name often just isn't necessary — even with people you know well. It's genuinely common for someone not to know a close friend's spouse's first name, because 형수님 (hyeongsunim, older brother's wife) or 제수씨 (jesussi, younger brother's wife) works perfectly as a form of address all on its own.

The Titles That Replace Names
| Title | Who it's for |
|---|---|
| 형수님 (hyeongsunim) | Your older brother's (or older male friend's) wife |
| 제수씨 (jesussi) | Your younger brother's (or younger male friend's) wife |
| 매형 (maehyeong) | An older sister's husband, from a male speaker |
| 형부 (hyeongbu) | An older sister's husband, from a female speaker |
These aren't reserved for actual blood in-laws either — they extend to close friends' spouses the same way 형/오빠/누나/언니 extend to non-family friends in the first place.

Why This Doesn't Feel Rude
It's the same logic behind calling a stranger 이모 at a restaurant — in Korean, a relationship-based title feels warmer and more respectful than a bare name, not less personal. The title says exactly how you two are connected; the name is almost beside the point.
When Names Do Matter
None of this means names disappear entirely. Official paperwork, introductions, and Korean name structure itself all matter plenty — and close one-on-one friends absolutely do use each other's names or nicknames. It's specifically in group, family-adjacent, and service contexts that titles take over.

Common Mistakes
Mistake #1 — Assuming this means Koreans are being cold or distant
The opposite is true — a title signals a warm, defined relationship, not a lack of closeness.
Mistake #2 — Assuming titles replace names 100% of the time
Close friends and family still use names and nicknames one-on-one; it's specifically group and relationship-marked contexts where titles take over.
