This drama is very refreshing. All the casts are so perfect for their respected role (I can't believe I saw Yi Kyung here!! I like him after I saw him at Eulachacha Waikiki). In the beginning, I was hesitated to watch due to some negative comments and the rating, however, I'm glad that I choose to watch it. I find this drama is so underrated! The youth theme is nicely embedded through the whole show. It's about the friendship of 5 people group and their journey to go after their dream, finding their self-identity and the true meaning of love. The story is more focused on Tae Oh, who is played by Min Ho (He acts way better here compared to his previous drama with Sulli. Or maybe because the character has more similarity with him??). He is a lonely guy who is neglected by his father and value his friendship on top of everything. However, compared with the rest of the group, he is in a better position. Even though he is neglected, he has no worry about his life or future. He can waste money without any worry nor he does not have to make any effort into anything. Which is why he desires something that can give him the spark. Something that can force him to lead a more interesting life. He wants something but he is a coward to make an effort for it. This was shown on the relationship between him and Song Yi. He knows he likes her, but he does not want to commit or make any true effort to pursue her either. He thinks that true love has to be sparkling, intense and brand new, but it does not need to be. Then he finds himself losing the girl to his best friend. The ending is bittersweet and realistic. Both he and Song Yi lost the chance to blossom their first love but I think through time, they will gain something more important. A lifelong friendship.
