It talks about a boy with special needs and after his father dies one night due to a heart attack, the dad's brother comes to the boys house and the boy teaches the uncle what the work is, obviously the relationship between the boy and the uncle was not good at first and also the fact that the boy's childhood friend cared a lot about him was amazing, but what was more amazing was that the uncle soon understood the boy and helped him and the friend also came to help him too and I recommend this tv show to everyone, second Korean drama I watched after watching Squid Game and don't regret that I watched it, absolutely amazing show😊.
