SEVENTEEN's Wonwoo surprised fans with a new song, 'Spring, Summer, Fall, Winter', released on July 17 at 6 PM KST through Pledis Entertainment in celebration of his birthday.
The track captures the feeling of cherished memories across all four seasons spent with a loved one, expressing a wish for those moments to continue. Wonwoo's warm vocal delivery adds to the song's emotional weight. A Japanese version titled 'Shunka Shuto' was also released alongside it.
This continues a tradition for Wonwoo, who previously released his solo track 'Gogae' on his birthday last year. He contributed to both the lyrics and composition of that single, which showcased his vocal range and ability to convey emotion.
Wonwoo began his mandatory military service in April 2025, becoming the second SEVENTEEN member to enlist. He is currently serving as a public service worker and is expected to be discharged in January 2027.
