I see people are rating this drama quite low. I don't agree with them. I was really surprised to know about such a bad attitude to it. I watched it when it was airing. I'm re-watching it now. And I'm enjoying it again. This is the case, when acting is, well I admit, not good. Especially Rain is awkward in this role. But the drama is made so good, easy, and heartwarming. There are not much of awkward tragedies, fightings, jerks, which I hate in dramas. Well, there are still jerk characters which i can't stand and just scroll their scenes. But it doesn't really spoil the heartwarming impression of the drama. It's not heavy and not overfilled with useless scenes. Kim Myung Soo's and Krystal's acting is quite great! I'm not a fan on these idols, but I loved them in this drama. I'm not a fan of Rain as well, but I don't really like him here (let him be just a model or an action actor, but romantic... omg is awkward for him). But it's still okay, as his character is quite fine person. Cha Ye Ryeon is also one the best in this drama. And the dog... It's really great to add such a beautiful dog in the cast! In spite of its flaws this drama have got a great director, artist and other creators team who made it still really enjoyable. This is the most important in any drama for me. Though I don't know anything about the team, but I can see their work: This is just a light drama to rest your mind when you need some fresh and sweet air ;)
