One cannot tell by the generic title that this is an entertaining, inspiring, warmhearted series about the hero's love for fellow humans, friends and family. It is also about perseverance, forgiveness and redemption. For me, it is an engrossing series to binge watch. I like Yoon Doo Joon from the "Let's Eat" series and he does a good job here too. He is a fine actor. I am not familiar with the main lead, Kwak Do Won but I am now a fan as he portrays very well a character who while experiencing adversity in life is still filled with exuberance. There is also a teen romance with all its angst. The other casts members were equally wonderful!
