Heartman: Rock and Love (2026)

Seung-min, once the lead singer of the college band Ambulance, now quietly runs a small instrument shop. His world flips when Bo-na, his legendary first love—the girl he never mustered the courage to confess to before she vanished—unexpectedly returns. As his heart starts racing again, old feelings flood back. But he’s stuck in a mortifying bind: there’s a secret Bo-na can never uncover, no matter what.
