Gayoon was in Junwan's cabin, briefing him on the case's progress.
"The boy's name was Shinho and he lived with his mother in a rented apartment," she informed him. "Her name was Choi Hyeri but her son's surname was Kang, indicating that she had given him his father's surname even though she was not married."
"How many men did she know with the surname, Kang?" Junwan asked.
"We only came across one," Gayoon replied. She put a picture on his desk. It was of Kang Danny.
"Isn't he the hotshot doctor?" Junwan frowned.
"Choi Hyerin used to work at his hospital," Gayoon stated. "And also, the sack we found with the body belongs to that same hospital. Kang Danny is known to be a casanova and Hyeri might have been his mistress for a time."
