Twenty Five Twenty One — Season 1
Against the backdrop of a devastating financial crisis that swept through the '90s, two young lives saw their aspirations shattered. Years later, fate reunites them – she’s 25, he's 21 – and amidst the uncertainty of navigating early adulthood, an unexpected connection blossoms. Finding solace and strength in one another, they forge a friendship that deepens into something more, offering hope and resilience as they face the challenges ahead together.

When the financial crisis threatened to shatter Na Hee-do’s aspirations, she resolved to seek a new beginning – a transfer to a school with a fencing program.

She met his gaze, determined to make the best of this first encounter. The complexities surrounding Back Yi-jin began to clarify.

When a fortunate opportunity arises, Hee-do implores her coach for additional instruction. An unexpected visitor arrives, hoping to see Yi-jin.

Seung-wan stood firm, resolute in the face of a teacher’s abuse. Around her, Hee-do and Yu-rim offered unwavering support to a teammate overwhelmed by distress.

The weight of personal connection pressed down on Yi-jin as the school fencing team prepared for its final competition together. This was more than just a match; it was a culmination of shared experiences, triumphs, and unspoken bonds forge…

Faced with a sudden family crisis, Yu-rim makes a decision that ignites public scrutiny.
