Synopsis

Twenty Five Twenty One (스물다섯 스물하나, 2022), Season 1 is a 16-episode Korean coming-of-age drama you can watch online on iFILM. Set against the late-1990s financial crisis, the season lets that very crash break two young people's plans before it quietly pushes them toward each other.

Na Hee-do dreams of fencing for real, but her school cuts the program, so she transfers to train alongside the national team's rising star. Back Yi-jin loses the comfortable life he knew when his family goes bankrupt, and takes any job that helps him start over. They meet by chance, and out of bickering, defeats and late-night talks grows something neither rushes to name. Around them the season tracks rivalry on the strip, the bond between five friends, and the cost of chasing a dream at the wrong moment.

This tvN hit, led by Kim Tae-ri and Nam Joo-hyuk, wins on tone rather than twists — warm, nostalgic, and now and then genuinely aching. If you love stories about first love and being young, this one rewards you. Stream Twenty Five Twenty One Season 1 online on iFILM.
