Ko Kyung-pyo Breaks Down on TV: His Mom's Illness Changed Everything

Actor Ko Kyung-pyo dropped the upbeat traveler act and went somewhere more honest on the August 2 episode of MBC's Nollercoaster, telling his castmates about his mother's illness and death for the first time. It's the kind of moment that reframes everything that came before it.

Ko lost his mother on September 26, 2020. He had spoken briefly about her in the aftermath, saying she was "the greatest presence in the world to me" and that he intended to live in a way that proved the love she gave him. On Nollercoaster, he went further: "After I heard about my mother's illness, my attitude toward life changed," he tells the group, adding that when he looks back, there are things he regrets. The specific regret, he ties to his time filming the beloved drama Reply 1988, though the details of what he actually did or didn't do remain his to tell when the episode airs.

Nollercoaster is a road trip variety show where No Hong-chul, chef Choi Kang-rok, Ko Kyung-pyo, and YouTuber Bbani Bottle toured five theme parks across Spain and Germany over a week, riding 56 attractions with a combined rail length of 14 km. Ko had played the role of the hyped-up youngest member the entire trip, so the gear shift to family confession lands with some weight.

The finale episode wraps with the crew riding Voltron, a roller coaster at Europe's top-ranked park that opened in 2024. It hits 100 km/h, pulls a 105-degree vertical launch, and packs in inversions and airtime in one continuous sequence. Ko called it a full stop, "the period at the end of the sentence." Bbani Bottle described it as fine dining for roller coaster fans. Whether either of them can top that hyperbole is a separate issue.

Ko also cooks for the group on the final day, something he'd been promising since before the trip started. He uses a recipe he says he doesn't share freely, and the show teases that chef Choi Kang-rok, who won a cooking survival competition, actually approved of it. Choi plays undercover sous chef for the occasion, disguising his professional skills to let Ko lead the kitchen. His suspiciously clean knife work doesn't go unnoticed.

There's also a parting shot from Choi at the end of the trip. He tells the younger members that "if different people join next time," implying he won't be back for a second season. The comment lands as a mild bombshell among the cast. Whether it's genuine or just good variety TV is the kind of question that only the next season announcement will answer.

Nollercoaster aired August 2 at 9:10 p.m. KST on MBC.
