This was a truly sad chapter, I like that we were able to see his grief not just as a child but even well enough into his teen years. While I get he wanted to stay for the dream both him and his dad had for him, it was extremely irresponsible for the best friend to leave him as a child all alone. Also one thing that had me like ehh was him asking Hyun to call him father. Like he wasn't a toddler when he lost his dad, he knew what was going on so to be asked to call someone who was his father's best friend, father just because he adopted him. Asking him to call him uncle or maybe a nickname would've been better.
