Padam Padam Episode 2

Kang Chil and Gook Soo are released from prison. Kang Chil is being followed and watched by the man who set him up in the first place, it seems. Ji Na has flashbacks of her past. We find out she blames her dad for her mother's death. Kang Chill and Ji Na often meet. Kang Chil's mother (I think it's his mother) ignores him. Gook Soo appears, starts beating up Kang Chil (which ultimately saves him). Kang Chil is getting his eyes patched up by Ji Na, whom he seems to mistake as someone else.
