Park Bo-gum and Sean Run for Korea's Liberation Day, With Bib Number '1945'

Singer Sean crossed the finish line of this year's 815 Run charity marathon on August 15, completing all 81.5 kilometers despite a right-leg injury sustained in July and, more recently, the loss of a toenail on his left foot two weeks before race day. Actor Park Bo-gum ran alongside him, and the image of the two moving in stride along the Han River, wearing running shirts embroidered with the Korean flag, circulated widely after both shared it through an outdoor brand's social media account.

The number printed on Sean's race bib was 1945, the year Korea was liberated from Japanese colonial rule, a detail that gave the photograph an added layer of resonance beyond the athletic achievement itself.

Sean has organized the 815 Run every year on Liberation Day as a fundraising effort for descendants of independence movement patriots, directing the proceeds toward improving their living conditions. The event's distance, 81.5 kilometers, mirrors the date: August 15. This year marked his seventh consecutive run, which he noted in a post he shared after finishing, writing that he had "safely delivered 81.5km" and adding a message of gratitude and remembrance directed at those who sacrificed for Korea's independence.

Completing the course while managing those injuries was a meaningful commitment. Sean had publicly disclosed both setbacks in the weeks leading up to the event, and his finishing the run intact drew genuine admiration from fans and followers.

Sean's record of public service work extends well beyond the annual marathon. He was a driving force behind the construction of a care hospital for ALS patients, which was completed last year, an effort that took years of fundraising and advocacy. Park Bo-gum, meanwhile, has participated in the 815 Run on multiple occasions and has his own sustained record of charitable giving.

The two's appearance together on Liberation Day has become something of a quiet tradition, low-key in its framing but pointed in what it chooses to mark.
