In a moving celebration of his milestone 30th birthday, SEVENTEEN member Wonwoo released a brand-new special solo track titled “Spring, Summer, Fall, Winter” on July 17, 2026, at 6:00 p.m. KST.
Rather than receiving gifts on his special day, the multi-talented artist turned the occasion into a gesture of gratitude by offering his fans, CARATs, a deeply personal and comforting musical release accompanied by an official music video.
A Seasonal Reflection on Shared Memories and Future Promises
The newly dropped track, “Spring, Summer, Fall, Winter,” serves as a poetic and introspective ballad that explores the passage of time through the lens of changing seasons.
Written with sincere emotion, the track centers on the experience of moving through the years side-by-side with someone special, holding tight to every shared moment regardless of how much time passes.
According to the official description provided in the release coverage, “Spring, Summer, Fall, Winter” is directly characterized as a song that reflects on the passage of time and enduring affection:
“’Spring, Summer, Fall, Winter’ is a heartfelt track that reflects on every season shared with a loved one while expressing the sincere hope that those precious memories will continue into the future.”
This central theme highlights the deep bond Wonwoo has cultivated with his fans over his career.

By using the natural cycle of the four seasons- spring blossoms, summer warmth, autumn leaves, and winter cold- as a central metaphor, the song highlights how steady and reliable love can be throughout life’s shifting phases.
The accompanying music video further enhances this reflective mood, pairing Wonwoo’s deep, warm vocal delivery with understated visual aesthetics that emphasize comfort, quiet contemplation, and artistic growth.
Celebrating Milestones Amidst Ongoing Group Success
Wonwoo’s surprise birthday release comes at a time of remarkable momentum for both himself and SEVENTEEN as a whole.
As a key member of the group’s celebrated Hip-Hop Unit, Wonwoo has consistently contributed to SEVENTEEN’s discography through his distinct low-register rapping, smooth vocals, and thoughtful lyricism.
His decision to drop a solo track on his birthday reflects a cherished tradition within SEVENTEEN, where individual members frequently release self-produced or special content to celebrate personal milestones directly with their fanbase.
The timing of the release also coincides with several major highlights across the group’s career activities:
- Contract Renewals: SEVENTEEN recently finalized their official contract renewals with their long-time agency, PLEDIS Entertainment, securing their future as a full group and reaffirming their strong commitment to continuing their journey together for years to come.
- Strong Chart Performance: The group continues to maintain a dominant presence on major Korean music metrics, frequently topping both weekly and midyear Circle Charts across physical album sales and digital streams, while consistently ranking high in monthly idol group brand reputation indices.
- Variety and Media Presence: Beyond music releases, Wonwoo has continued to connect with audiences through various broadcast and travel programs, such as tvN’s popular variety series “NANA TOUR with SEVENTEEN,” which showcases the group’s genuine camaraderie and off-stage personalities.
By releasing “Spring, Summer, Fall, Winter,” Wonwoo has created a lasting birthday moment that resonates far beyond a single day.
The track stands as both a quiet thank-you note to the fans who have supported him through every season of his career and a gentle promise that the journey ahead will continue together.
