Love 911

Kang-il is a rescue firefighter whose wife died while he was helping someone else in an accident. Struggling with guilt for being unable to save his wife, Kang-il frantically jumps into dangers to rescue others. Mi-soo, a doctor at a general hospital, makes a misdiagnosis and gets sued by the patient's husband when the patient ends up slipping into a critical condition. In danger of losing her medical license, Mi-soo's lawyer advises her to convince Kang-il to testify against the patient's husband for an assault that occurred while the husband was in grief. She sets out to win Kang-il over by "dating him."
