High Points: Hyung has come back to Korea and sees his family briefly. He promises to take Grandpa to the aquarium and doesn't show, but Gramps is happy to have Soo-young take him. Hyung comes to work impersonating Min-suk impersonating Hyung-suk. No, he doesn't really try to impersonate anyone. He just acts distant. When he tells CEO Yoo that he has tricked him and now owns the company, CEO collapses and spends the rest of the episode in the hospital. Grandpa disappears. The rest of them go looking for him, but he has passed away.
What were they thinking? Hyung has been away from his family so long he is cold and embittered. He only sees them once. Min-suk has been living with a very caring dad and is a much warmer and happy person. Jin-woo has come to appreciate Min-suk and appeals to him for help but he's already talked to hyung and failed. Probably the only thing that could make a difference is the passing of the grandfather.
High Points: We start with the memorial for Grandpa, and there is a heart-rending montage of scenes remembering him. Hyung changes his mind, returns the money, and heads back to Germany. Min-suk plays hockey again before he is completely healed, and gets permanently injured this time. Why on earth did his coach let him play? He and Soo-young meet her friend and go out to dinner, and she has to pay for him. She goes to take care of her mom and misses Dad's birthday and won't explain, so they get into an argument and he stalks off.
What were they thinking? Min-suk is feeling the impact of the age gap. He's only a kid and can't keep up with the adults. He feels bad that he doesn't have a job and money, and is hurt that Soo-young won't confide in him, but he couldn't help her anyway. He has a nice bonding scene with Jun-woo, but he still acts like a dongsaeng and pesters him for the last piece of fried chicken.
