For example, the way that it was revealed how Kou's mother passed away and that was this was why it affected his studies and his personality. Also, everything that the two main characters did was so off-putting. Just the way the story was running did not make sense or settle well for me.

Really, the subplot with Narumi was really badly made. I don't think Kou made a mistake trying to be there for her, it was just like his character, but the fact he turned down Futaba without explaining anything is just werid. Really, he never had any feelings for Narumi, why make Futaba think he doesn't love her? I understand why he couldn't be with her before Narumi settles in but turing cold shoulder like that is so confusing. And then it just went worse and worse. All his actions were as he was really a jerk trying to keep a girl around him even though he had no intentions on being with her. I don't think that it's possible to change boyfriends so easily like Futaba did too. Maybe it's the way mangaka showed their relationship but I feel like she was happier with Kikuchi. After how Kou acted, I don't know how could she so easily trust him again and just ignore the months she was with another. And then the accident happened. Come on, that was just too much.
If it ended there, I wouls probably give 6. But I really like the plot twist with the dream. I almost cried my heart out and noticed how much I liked the characters.
I also like how the triangle Yuichi-Murano-Aya ended. It was a good description of love towards a teacher and I really like the crybaby Aya and his honesty. Murano was a bit stiff for me, I didn't like her much. Yuuri was ok. But the best was Kikuchi. I like both him and Kou, so it was hard time to choose between them. Mangaka had me there for awhile, making him such a great guy, I really though maybe Futaba will break the shoujo manga rule of staying faithfull to the first guy. Well, mangaka made him look like Taemin, so I am not surprised at all I was cheering for him. Couldn't she have both? ;p

I'm glad Futaba and Kou end up together in the end. I found them both to be really likeable. Though it would have been nice to see it happen a bit earlier than it did. Her reasoning for realizing her feelings were nice, but I noticed that all that happened on the School Trip seem to not really affect why she decided she was still in love with him that much. When reading I was kind expecting it to happen then, not a few chapters later. Though it was a nice ending for them.

I love that Shuuko and Kominato ended up together. I understand why she liked Kou's brother, but found that her and Kominato were better matched even before finding out they got together. She luckily figures out that he's such a great guy and falls for him. The guy deserves it and I found her to be a really likeable character as well. The other girls changed her for the better.

It was nice to see Yuuri get a man herself. She was adorable.

I'd say the only flaw was Futaba made me frustrated because of how fickle she was, but hey that's the drama for them to realize they love each other so it's okay.

Oh and towards the end, the author trolls you for a few pages by making it seem like Kou died from being hit by the car. Don't fall for it. XD
