GOOD;

- Silly tone and clichés well managed making the whole thing fun to watch.
- The main actors : if not for Ahn Hyo Seop and Kim Se Jeong, I would have dropped this. Their chemistry is very good. physically I liked the couple they make: not siblings like. Different physical features. It made them magic on screen.
- The two main leads: Kang Tae Moo and Shin Ha Ri. Their interactions are silly and funny but also meaningful at times. A few cringe moments but they are so cute I will forgive that.
- Second couple is decent. They have their own story and challenges. They are a more mature couple compared to the main couple so I don't really mind their story closes with an "open ending".
- The parents and bro of Shin Ha Ri. They are the funny elements.
- Lee Min Woo and his gf: a rather realistic and sorry couple but I liked them. They are like some couple really are in real life.

NOT SO GOOD:
- No character's depth of psychology
- No character's development apart for SFL with a small one
- Team developpers 1 was ok but a bit too much at times.
- Grandpa and president Kang : a lot of potential wasted here. The last ep brought some fun moments but It could have been better.
- Ending a bit rushed.

OVERALL: A very silly and fun drama to watch if you want to smile and laugh but not a very memorable one. The story is full of clichés and there is not development to really make the characters stick in your mind. 9/10 for the fun ride.
