On this day, Ko Eun Byul called Han Yi Han and said that she was going to go in front of the gym.  Yi Ahn who had been in front of Eun Byul's house ran to the gym and then leisurely came back outside.  The two looked at each other and smile as they were playing video games and had a fun time.

As the night got darker, the two people were on a park bench together. 

At this time, Ko Eun Byul misstepped and fell down by accident.  Yi Ahn was surprised and raised her up after being surprised. At this time, they found a scar on Ko Eun Byul's arm.  Lee Ahn said, "I didn't see this scar.  When was it formed?"
