Let me start off by saying I didn't expect to love this drama the way that I did. It took awhile for it to really intrigue me. Like most people have mentioned, it wasn't until after the first few episodes where I found myself more invested in the story. Though I did enjoy the first few couple episodes despite some of the second hand embarrassment. But after recently watching the writer's previous drama, Marriage, Not Dating, I can see that's totally her style. lol I found myself relating a lot to Eun Hwan Gi because I myself am a shy, introverted person. This is drama land so of course there's going to be some over exaggeration, but his inner monologues, having trouble speaking in front of large groups of people, avoiding social interaction, being able to notice small details, preferring to be by himself...that's what being an introvert person is. There may be some social anxiety mixed in his introverted personality as well which does happen. As for the black hoodie, they gave a reason as to why he started to wear it. So when you watch this drama, I wouldn't take the title too literally, but it makes sense why that's the title. This is rare in dramas, but I pretty much liked every character. The cast had great chemistry and it was really fun and enjoyable to watch. The two leads were especially adorable to watch onscreen. They played off each other well. Opposites totally attract in this drama. Btw, I understand not all extroverted people come across as loud and annoying as Chae Ro Woon sometimes did, just as all introverted people are not all like Hwan Gi, but when you pair the two together, it kind of makes sense that you would see that play out a lot like how it did in this drama. In spite of all this, I didn't particularly like a certain storyline. I felt like it wasn't a good enough reason to justify a certain someone's action. I think this drama was meant to be 20 episodes, so maybe when they did the rewrite it kind of screwed that part up a bit? But overall, I did enjoy this drama a lot and totally recommend it. Also, the OST is 10/10! It's hard not to fall in love with every song you hear play throughout it.
