Finally Seok Hwan got to Iren's house and knocked on the door, then Iren opened the door and told Seok Hwan to come in. in the living room there was already Iren's father who was observing CCTV that was in the school at the time of the accident. Seok Hwan was surprised and said "how can you have a CCTV video of the school when I was looking at it when there was no security?" Iren's father replied "have you forgotten that Uncle is a computer expert". Seok Hwan just remembered that Iren's father is the existing governance in his school and as well as holding the school computer, no wonder that Iren's father got the school CCTV video.
The three of them also watched the school video and found someone entering in a Black jacket and wearing a mask into the hall, while Seok Hwan was still singing he picked up Iren's phone and recorded the ringtone (plus the lost HP was unlocked making it easier for the actor to record). They are still looking for other evidence and looking for who the perpetrator really is because the face of the perpetrator is not visible.
It did not feel like Seok Hwan was late in the afternoon and immediately went home.....
On the way home Seok Hwan sees Kang Joon with a man. (Kang Joon is an arrogant boy in school). "He looked suspicious, what was he doing with someone in a deserted place" Seok Hwan said suspiciously. Seok Hwan attempts to eavesdrop on their conversation and sees Kang joon giving money to the man. "I have to tell Irene" (inwardly).
Seok Hwan ran to the house and immediately prepared for dinner. At dinner Seok Hwan's father asked how the results of his investigation, then Seok Hwan explained the results of his investigation so that it made his parents amazed. His father advised him to be careful when investigating, because we do not know how the whole situation and behavior of a person is different.
