I just noticed something. When Chairman Shin had an artificial heart surgery in Season 1 that was released in 2016, it was mentioned that his age was 72. Now in Season 2, in episode 1, it was revealed that his birthdate was July 2, 1948 and died on June 26, 2019. By the time he had a surgery in 2016, he was supposed to be 68 years old and not 72. It was a minor mistake, though. Still, the information must have been corrected.
Another thing that I was wondering about was the message that Chairman Shin was about to tell Teacher Kim. He told his manager (Manager Joo) that he'd just tell him after his surgery. What was it? Did I miss something? I hope someone can answer this. I'd appreciate it. I'm just hooked up with this drama. Anyway, I enjoyed the first season. I just started watching Season 2. I look forward to seeing more cases. Kudos to the team! ๐โ
