Good Boy episode 12 recap: What is Yoon Dong-ju’s punch-drunk syndrome?
Yoon Dong-ju is known as one of the best boxers and has suffered several injuries. During one of his matches as a national team player, he was hit in the head near his eye. The injuries cause him headaches and dizziness.
However, if Yoon Dong-ju keeps receiving head injuries, his optic nerve could be damaged, potentially leading to blindness. In episode 12 of Good Boy, Yoon Dong-ju showed signs of punch-drunk syndrome but chose to keep it to himself. Despite Ji Han-na asking about his health, he refused to open up.
When Oh Jung-gu found and beat up Yoon Dong-ju, he revealed that he was aware of how Dong-ju was supposed to pay Lee Gyeong-il's medical bills. However, now he ended up looking after Lee Gyeong-il's mother and nursing her at the hospital.
Oh Jung-gu revealed that he knew that after one of the matches, Yoon Dong-ju found out about punch-drunk syndrome and how it affects his eyes. Oh Jung-gu also stated that despite knowing why Yoon took those medications before the match, he did not help testify in his favor when he was accused of doping.
After hearing Oh Jung-gu’s words, Yoon Dong-ju became furious, as he used to be his coach back in the day. He tried to fight back but could not, and Oh Jung-gu won the fight. It is yet to be seen how Yoon Dong-ju will recover from the wounds that occurred during this fight and the stabbing incident.
Meanwhile, Good Boy episodes 13 and 14 are scheduled to be released in the coming Saturday and Sunday on JTBC and the OTT platform Prime Video.
