About
"Youthful ambition and first love against hard times"
Set in South Korea in the late 1990s amid the aftermath of the Asian financial crisis, this coming-of-age romance follows a driven teenage fencer chasing an Olympic dream and a young man forced to abandon his own future when his family's fortune collapses. Told partly through a framing device looking back on the friendship, it's warm, nostalgic, and full of youthful energy, mixing sports-drama grit with slow-burn romantic tension. The pacing is unhurried and character-driven, leaning on charming performances and era-specific detail rather than plot twists, though its final stretch has divided viewers.
the charming lead performances and nostalgic, era-specific coming-of-age atmosphere.
you want a tidy, universally beloved ending rather than a bittersweet one.
