This drama really charmed the socks off me. I really liked having a drama finally focusing on some "good guys" for a change, instead of introducing a horrible chaebol heir seeing the error of his ways due to some candy. My Rating: 9.0 In Short: I really liked the premise of this, It's simple, but original and effective, and gives off a "slice of life" vibe that I enjoyed. I also liked the cast, particularly our "lock and key" couple. Pros: A realistic view of relationships in four different age groups, with a refreshing cast, great music and lots of charm. I also really liked the 14-episode format. For me, even 16 episodes can sometimes be way too long. Cons: I would have liked to see even more interactions between the boys, not just their lives outside of home. I feel like the great scenes in the last episode really show us the potential in this. After all, five people who live together are bound to interact and influence each other a lot.
