He was the best surgeon among the musicians, and the best singer among surgeons.
After becoming Ji Yunya's assistant, his personality toned down a bit. However, he still got into quite a bit of mischief. Upon discovering Dr. Nyx's true identity, he pursued her relentlessly. Ji Yunya naturally dismissed him, but Jack was determined. Believing in the saying "a close relationship with superiors helps get things done," he applied for the assistant position under Dr. Nyx and ultimately succeeded. When Ji Yunya found out Jack was appointed, she went out of her way to make things difficult for him. Being the most outstanding graduate of the medical school, Jack navigated her challenges flawlessly. Eventually, Ji Yunya started to value his talent, and they developed a mutual understanding, leading Jack to stay by her side.
As an assistant, Jack was impeccable. As a friend, he was equally competent, often adding much-needed humor to her otherwise monotonous life.
