The two meet again due to Eun Ok losing consciousness during dialysis. As their meetings continue, Oh Ryu begins to feel both affection and guilt towards Eun Ok. On the day Oh Ryu tells Moo Saeng that he wants to quit the job involving Eun Ok, he discovers that Eun Ok actually doesn't have any money.
