I rarely write reviews, but I just feel like this is one of those dramas where I need to express my opinion in one long post, so here I am!! I'll write this review in sections so it doesn't end up all over the place...

1. Story
The story was a very interesting one in my opinion. However, there's one thing that bothers me the most about it, and that is how hollow it ended up... They tried to make it deep and emotional, but with only 5 episodes, they failed. They had no time to show us everything they wanted to and I feel like it would've been so much better and deeper if they added at least 2 episodes!
That's the biggest flaw of this series, trying to achieve the depth it didn't have time to achieve.

2. Acting & Cast
If one thing was absolutely perfect here, then it's the acting!
The actors portrayed their characters with perfect facial expressions, voice tones, actions, and everything that goes along. It felt so natural and raw that I couldn't help but want more of it...
Whoever did the casting, THANK YOU!

3. Romance
The romance here is yet another factor that was affected by the fast pace of the show as well as YoonDae's and SooHyuk's relationship... It came so suddenly and didn't feel real at all... It even felt forced due to the characters not having enough time to form a romantic relationship. No matter how hard I tried, I couldn't see romantic feelings for the other in either of them.

4. Ending & Overall
Despite my mostly negative review, I enjoyed this series a lot!
I liked how realistic and serious it was, along with the stepbrothers' storyline which almost always ends up tragically...
As for the ending, I know it's supposed to be an open one, but it's also one of the reasons I wish we got a few more episodes. It just felt rushed and I didn't feel like any of the problems with their parents actually got resolved....

5. Conclusion
For me, it's a strong 8/10. However, if it had more episodes to deepen the story, I would've surely rated it much higher!
