Sunu, beautiful as always.
What happened
ENHYPEN's SUNOO turns Replay's older-woman address into playful age-role responses from fans. The 26-second official short uses the song's Korean title and includes its English refrain in the supplied captions.
Why Koreans care
누나 (noona, older sister or older female acquaintance) is used by a male speaker, while 오빠 (oppa, older brother or older male acquaintance) is used by a female speaker. Fans play with those relative-age positions: one rejects being the older woman, while another embraces that role.
In the Korean comments
One fan reverses the age address: “I'm not older than you... oppa” (fandom). Another turns the song's compliment back toward SUNOO: “Damn, you're prettier” (fandom).
What the words mean
The reference is to SHINee's existing song Replay, not evidence of a newly released SUNOO single. The age-role replies engage with the song's older-woman premise; they do not establish actual family ties or romantic relationships.
