There must be a reason they set the two houses (gunwoo's and Kim Joon's son's) on two sides of a narrow alley. The car that hit Gunwoo must have been speeding there. Here is my theory: Seon Yeol's father owed a favor to Kim Joon, and he was sent to scare his mistress and hush her about his illegitimate child / or slush fund. So, in that alley Seon Yeol's father drove his car toward the mother and child, she saved his son, but just then Gunwoo went out and the car hit him. Seon Yeol's father didn't see him cause he was looking at the mistress and the illegitimate child. Gunwoo didn't see the car, cause he was looking to whoever he was running after. It was an accident, it was a simple duty, but Gunwoo made it complicated. So Seon Yeol's father said "He should have gone and died in another place, not in front of his car" I believe the driver was Seon Yeol's father. He might have tried to help Gunwoo after the accident and Kim Joon made him stop and have him dump the injured kid for not to make the situation more complicated, to send the message to his mistress, or cause it was Suho's child, the problematic reporter for him.
