SEVENTEEN member Wonwoo turned his 30th birthday into a full fandom moment, quietly dropping the solo ballad Spring, Summer, Fall, Winter while serving in the military. Branded as a digital album, the release arrived as a surprise gift that instantly became the center of CARAT timelines.
Released July 17 at 6 p.m. KST, Wonwoo Spring Summer Fall Winter lands exactly one year after his self-written birthday single Gogae, turning July 17 into an unofficial Wonwoo solo holiday. This time, the focus is on a four seasons love story that feels tailor-made for fans waiting through his enlistment.
Wonwoo ‘Spring Summer Fall Winter’ Release: What, When, Where
The digital album Spring, Summer, Fall, Winter dropped on July 17, 2026 at 6 p.m. KST, which hit at about 5 a.m. ET and 2 a.m. PT for US fans. The release includes two tracks, a Korean version and a Japanese version, both available on major platforms like Spotify, Apple Music, and YouTube.
Pledis announced the drop through Weverse as a birthday present for CARAT, even while Wonwoo is serving his mandatory duty as a public service worker after enlisting on April 3, 2025. An official music video accompanies the track, so the “digital album” moment plays like a mini solo comeback rather than a quiet side release.
A Four Seasons Love Letter: Sound, Lyrics, Fan Reaction
Musically, Spring, Summer, Fall, Winter is a ballad built on restrained band sounds, with drums, bass, guitar, and piano wrapped in rich strings. Korean outlets describe the atmosphere as calm but deep, giving Wonwoo’s plain, unfiltered tone room to sit right at the center of the song.
Lyrically, the track looks back on spring, summer, fall, and winter spent with someone precious, then wishes that those memories will keep going into the future. That mix of nostalgia and promise is hitting fans hard during his service, with Reddit listeners calling the almost five minute song comforting and “like a hug,” and organizing streaming parties around both language versions.
From ‘Gogae’ To Military Era: What This Track Signals Next
Last year’s birthday single Gogae, which Wonwoo helped write and compose, compared life to climbing a hill and framed him as a sincere storyteller. Paired with earlier solo moments like “99.9% (WONWOO Solo)” and his emotional turn on JxW’s “Leftover,” his new four seasons ballad feels less like a one off and more like another chapter in a slowly building solo arc.
During a service period expected to end January 2, 2027, releasing a warm, time focused song in two languages reads like a promise to stay beside CARAT through every season until he returns. There is no official post discharge solo project announced yet, but working with veteran ballad creators while keeping his emotional core intact suggests that the Wonwoo who comes back could lean even further into this steady, band backed storyteller lane.
