My Bias Gets on the Last Train

Every night, Yeo-un rides the last train home—same route, same time, the same quiet routine. But one thing breaks the monotony: a girl with a guitar, whose presence lingers in his thoughts long after the ride ends. A shared love for the indie band Long Afternoon sparks their first conversation, and soon their late-night encounters begin to blossom into something deeper. Yet Hae-in isn’t just another devoted fan—she’s the hidden voice behind the band, carrying a secret she cannot reveal. As music draws them closer, the truth threatens to tear them apart. When the final note fades, will their story resolve in harmony… or end in heartbreak?
