JaeKyung's upbringing was rocky from an early age. The final heartbreak was hearing his mom say, Never contact me again. I appreciate the coach and his wife showing him love and compassion. People process heartbreak differently; he turned into a problem almost immediately after that conversation. He needed an outlet for all that anger and started making bad choices. The coach showed up again, speaking words of honesty and guiding him in the right direction. Who knows, had his mom had a different response, he might be different. We know his backstory, and I understand the reason he's this way. However, the way he treated Doc Dan isn't right.

I have sympathy for Jk because no child deserves this type of treatment, and I understand why he acts this way. Everyone handles trauma differently. I'm glad that the director and his wife came into his life when he needed them the most. Sadly, he treats Doc like his father treated him, and that's a problem. He has to know how he felt when his dad hurt him. Doc Dan will give him another chance because they need each other, and he's a good person. JK needs to prove he's not like his dad and earn Doc Dan's trust again.

Although he's tried to distance himself from Joo Jaekyung, it's not happening. He has now found someone from his past who may help him understand Joo Jaekyung better.
Whether I like it or not, Kim Dan will help JJ train because he's a good person, and they will become even closer. It's Kim Dan's choice, I hope he doesn't regret that decision.
The coach is right, fame and money mean nothing without having a purpose in life. Every decision made since becoming famous has carried consequences; for once, he needs to choose his next move carefully.
