The Second Hour of Yesterday | JJK KTH

One explosive, bitter night in a cramped rookie dorm shatters what was meant to be a brotherhood. Driven by the suffocating fear of failure, seventeen-year-old Jungkook snaps-hurling venomous truths at his exhausted group before running out into the freezing night. The fracture sets off a catastrophic domino effect, unravelling their lives into the darkest, most tragic timeline: broken bonds, missing members, and devastating losses that leave Jungkook suffocating under the crushing weight of his own guilt.

Unable to live with the wreckage he caused, Jungkook leaps into the void-only for time to freeze mid-fall.

A cosmic entity grants him a second chance, but with a cruel caveat: major events cannot be erased. Sent back to the timeline after the initial explosion occurred, Jungkook must navigate a broken reality to actively piece his family back together. Armed with the memories of a ruined future, he embarks on a desperate path toward redemption. Along the way, his bond with Taehyung shifts from a toxic coping mechanism into a profound, healing love-one Jungkook vows never to fully confess until every single member is saved, healed, and standing together once more.
