It started well until Mr Cha was buried under the school. The part where he was trying not to be discovered was funny but it went on for too long that it wasnt funny anymore. The construction guy was also not funny. Mr Cha was so clueless and his arguments with his manager were annoying that near the end of the show i just want him to stay buried there. I was hoping he will have this big revelation about himself esp when his wife called and they even have this weird sequence of his trying to think, but there was none. When he got rescued, it was just nothing special. Even the ending was not satisfying.
