It Would Be Great if You Didn't Exist

When did she meet her ideal girl in the worst situation?
Guk-Hwa was kissed by Jang-Mi and left. After a few days since that incident, Guk-Hwa left her work to go home, and saw Jang-Mi on the other train and tried to get off to meet her, while thinking "Why did I do that? The guy thing is already solved anyways."
Jang-Mi finishes working at her place, and gets pissed off because she keeps thinking about that fight about the guy. And so she gets off work all pissed off because Guk-Hwa keeps popping up on her mind again.
