Mr. Heart (2020)

Despite the fact that things just never seem to go his way, Sang Ha always manages to find a reason to smile. A remarkable member of the school track team, he admires Jin Won from afar. Jin Won, on the other hand, is his exact opposite. A record breaking marathon runner in high school, he is well on his way to becoming a marathon superstar. Determined to live up to the expectations of his coaches and colleagues, Jin Won cares about one thing and one thing only: running his next race. When he finds himself struggling to maintain his record-breaking stats, his coach suggests Sang Ha step in to help as a pacemaker. Disappointed in the coach's decision, Jin Won is anything but friendly to his new partner but with time and determination, the two runners come to find they share a similar passion, both on the track and off.
