Seventeen's Wonwoo drops birthday single 'Spring, Summer, Autumn, Winter' with Japanese version

Seventeen's Wonwoo released the digital single 봄, 여름, 가을, 겨울 (Spring, Summer, Autumn, Winter) on July 17 at 6 PM, his birthday. A Japanese-language version, 春夏秋冬 (Japanese Ver.), came on the same single.

Pledis Entertainment describes the track as warm-toned, built around restrained instrumentation and rich strings layered under Wonwoo's plain vocals. The lyrics explore wanting to remember every season spent with a loved one and hoping that time keeps going. The Japanese version was prepared to share the song's emotion with fans across more countries.

Last year on July 17, he released 고개, a piano-and-strings ballad he co-wrote and co-composed. This marks his second straight birthday solo drop. His solo catalog also includes 휴지통 from the Jeonghan X Wonwoo single album and 99.9% (WONWOO Solo) from Seventeen's fifth full-length album.

Wonwoo enlisted as a social service worker in April of last year—the second Seventeen member to enlist—and is scheduled for discharge in January 2027. Birthday releases while in service: apparently his thing now.
