My important viewpoints in sequence 1.Acting/Cast KIDS: Excellence,my main reason why I had to WATCH this drama till the end. They made themselves really lovable. Their situation made you care for them. The maknae was the best,she made me laugh,smile,cry,worry...etc. FATHER: According to the story he's emotional intelligence is really low, which somehow fitted the actor nicely. HOUSEKEEPER: Had a really weird and interesting nature,though her emotions were well-expressed in her eyes.(you have to watch this drama to understand it:) 2ND LEADS: also fitted their own roles. Except Seo Kang Joon who looked too old for his role or maybe it was Park Ji Bin who looked too young,(spoiler) they were the same age. 2.Story Veryveryvery melodramatic storyline from their past. 1st half:nice tempo, interesting middle:shock almost the end:tense,action movie-like ending:weird Bloomer-The story behind the mothers death was unacceptable!!!!!! I wouldn't have a mother if it worked like that in real life(sorry to put in some personal issues here,but that just got me REALY annoyed). 3.Rewatch value I'm not in favor of melodrama dramas. But the 1st half had a lot of cute and funny scenes. 4.Music It was well-fitted, there weren't any out-of-mood songs. Outstanding songs: Lim Kim-I'm Asking You, Kim So Hyun-First Love BTW:1st review EVER,so I hope it was helpful. For already-seen-this-drama-readers,feel free to comment on my review:)
