When did she meet her ideal girl in the worst situation?

Guk-Hwa was kissed by Jang-Mi and left. After a few days after 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 with the guy. And so she gets off work all pissed off because Guk-Hwa keeps popping up on her mind again.
