I had watched Zac Efron's version few years ago and liked it. I picked this K-drama randomly until I checked the plot synopsis after watching the 1st episode and decided to give it a chance. I think the drama outdoes the movie because of the runtime and also have a balance between comedy and drama which makes it deeper. I binged it in 3 days. And the standout performance was of Lee do Hyun. I liked him in Sweet Home but here he shows his range while playing a 37 year old and 18 year old version of the same character. He had incredible chemistry with his kids as their friend and father. Episode 8 and 14 were really emotional. I liked the moments between the main character and his father and also between the main character and his mother and mother in law. The drama is slow at times. Also the main character's best friend's creepy behaviour was romantisiced when he hits on the school principal which was justified becuase their was another character more creepy than him. Overall I still enjoyed the drama.
