Later, Myung-woo discovers the stolen purse, but just as he picks it up, Kyung-jin spots him and tries to arrest him again. Kyung-jin is then given the job of escorting Myung-woo through a dangerous district, only to be distracted when she tries to break up a meeting between Russian Mafia and Korean gangsters. With Myung-woo handcuffed to her, Kyung-jin almost single-handedly brings down the two rival gangs.

after Myung-woo is accidentally shot and killed by another officer as Kyung-jin chases after a criminal. Kyung-jin falls into a suicidal depression over his death and attempts to kill herself several times, finally almost succeeding when she throws herself off a building, only to be saved when a giant balloon floats under her. Soon after, she experiences visitations from Myung-woo, who appears as the wind, sending her messages and, at one point, he even appears in her dreams in order to give her the will to live after she is nearly shot to death by a criminal.
