Never a dull moment in this series! There's no doubt that I'd fall in love with the main characters but I was surprisingly attached to the supporting ones too! The RiRi couple has a very stunning visuals that I'll never get tired of looking at. I also like how funny and innocent some of the characters are which perfectly balances the drama. Also, this series makes me want to experience the beauty of South Korea and Switzerland, and even more curious about North Korea. The story made me realize that anyone could be your family if we just understand, love and respect one another. Even though the person seems like a stonehearted one, there will always be a possibility for him/her to change or show compassion and even better, love. Overall, it's fun and easy to watch.
