I watched this one right after it aired cuz everybody was saying it was one of the best, the couple was cute and so on... They were cute indeed. But only in the first half of the show. From the moment they break up that's when things start to crumble.

- When the series begins taeyang made up her mind as to stop pitying and punishing herself for what happened between her and taejoon's sister. So she decided to come back to badminton. But when junyoung comes back and taeyang has to face her (and this ends up breaking her relationship with taejoon, and consequently her happiness), I thought that at some point she would realize that she's again punishing herself for smth that she had already done what she could to apologize for it. She had asked for forgiveness and retired, what else did junyoung want from taeyang?! So I thought that taeyang herself would stop all of that, just think about herself, and continue her life with taejoon by her side (since he himself wasn't giving a damn for all this drama). But the writers chose to extend all of this drama and made the couple get back together like in the last minutes of the last episode. Honestly, what was that ending really?! Just for the record, junyoung is the most annoying character and taeyang didn't do anything bad. It was just the people around her that made it look that way. And I understand that his parents not supporting their relationship might be smth that could made her uncomfortable. But she had already did what she could've done for something she wasn't even that much guilty for.
- The series also drags A LOT this drama between taeyang, taejoon and junyoung. It's like after it begins it becomes the only story that's being told for some eps. I think all of it could've been wrapped up faster so that other things could be talked about. Like taejoon's problem with his parents, and taeyang's reunion with her mother and sister. But I also think all that drama around taeyang shouldn't have taken too long bc it wasn't that much big of a deal. Like I said, it wasn't taeyang's fault what happened with junyoung. Yeah, it was taeyang who insisted on junyoung going out, and yeah, taeyang didn't immediately take up the responsability for what happened. But it was a fatality still. So I think it was a bit too much that everybody was blaming taeyang for an accident. Especially junyoung who was taeyang's friend and the only one who was there.
- I think that taejoon's problems with his family should've been addressed. It was clear that his parents cared a little too much for their daughter's feelings and not about how taejoon was feeling. Taejoon loved taeyang, but when his family found out about their relationship of course he was considered a betrayer. And taejoon never really said anything about nothing. He never complains or says how he feels. He just understands everybody. That annoyed me. All of them should've had a talk about this. And in the end it wasn't clear for me if his parents would stop putting difference between their children. And since the drama didn't show that, it's my opinion that his parents will just accept his relationship with taeyang because his sister decided to be okay with that.
- One thing that annoyed me a lot was how whenever taeyang was sad (which after their break up was like most of the time) she would ghost taejoon completely and leave him all worried bout her. Like she even spent WEEKS without talking with him, not saying a word if she was fine or anything. And when she decided to come back to training he acted like nothing had happened and everything was okay. It was so infuriating for me! He was too good for her. I remember a scene of them talking about feeling lonely and I thought that they would grow to be the emotional support of each other. But that wasn't what happened. Taeyang avoided everyone whenever she was sad and he just hid all that he was feeling. At least that's how it felt for me.
- But I admit I liked taeyang and taejoon as a couple in the first half. They were cute, supporting each other in the challenges of their career. Taejoon is just perfect. And taeyang was light and fun. Unfortunately all of this changed at some point.
- I think the only thing I really liked from beginning to end in this drama was yumin. She was my favorite character! Maybe bc she was removed from all the drama. But she's also not complicated. She's just herself. I also liked her relationship with junghwan. Yeah, he took too long to get over his ex. Yes that's super annoying. And yeah I totally get people not liking their relationship. But they were so freaking cute together! And I liked that she put some limits, not going after him and just walking away when she sees he's taking too long to get over. And in the end he went for her. Idk, I just think they were so cute together.

Anyways, for me this was an overrated drama. The beginning was very promising but all went downhill with their break up and taeyang's past coming back. Maybe if the series didn't focus so much on the taeyang/junyoung drama and more on the messages that were trying to be passed on, the side characters dramas and the romance, maybe I would've liked more. And my rating is not lower than this just because the first half was really good.
