After reread this manga I just realized




Jung's father was brainwashed and manipulated by Inho's grandfather even after his death.
Instead of solving Jung and his father's mental problem, this so called professer just took advantage of them for his own sake. He was professional and psychologist of Jung's father. He was fully trusted and respected by him. The professor definitely knew what would happen to Jung after his "advice" but he still kept brainwashing Jung's father and made him believe that Jung need to be suppressed rather than understood and loved.
Just like Jung's mother thought, this professor deliberately provide wrong advices to make Jung's father look after his grandchildren. He must know the personality of Inho's auntie and what would happened after his death so he just ruined Jung's family and life for the sake of his grandchildren.
The professor was calculative but he should know that karma is a bitch. If Jung did get proper treatment at young age, he wouldn't manipulate other people to ruin Inho's hand.
