What attracted me to this drama was the borderline incest. I know, I'm weird but there's something fascinating about that!
The issue I had with this drama was that nothing really happens?
If people are that worried about the 'incest' part, don't be because Haruka does not realise it himself that his actions are because he is in love with her, not because she is his younger sister.
I found Haruka so damn good looking! He gave me tsundere vibes and I love how he is just soooooo sweet to Setoka.
Setoka on the other hand is a type of female character I don't really like. Falls in love with boys too easily, but in  a way I liked her positive attitude, which is the reason why she is so bullet proof to males rejecting her love confessions.
The other love interests for Setoka were appealing to the eyes, but their characters were not developed well enough for me to really care about them. Yes, they are love rivals, but let's be real, I'm rooting for Haruka to get Setoka!
Overall, it is good and very short drama to watch!
