Neenee is the only reason that I kept reading this stuff, wasn't she the main heroine in the first place? So why didn't she show up for like, 30 chapters or so? Then when she did she was turned into some villian? That's just not cool. And I really, really hate Riku now. Soon after Neenee declared her love to him (without him saying anything back) and then got killed trying to save him, he replaced her with Rena, saying "I don't care anymore about the past". Plus after all that, he finally meet up with Neenee, without asking any reason as to how she became that way and why she did what she did he started to freak out on her. The thing is, to Neenee her whole world is about Riku who only used her so he could meet up with his lost lover when she grows up, just when he realized he might actually feel something for Neenee as well he gives her up as dead (without even bothering to search for her or consider her alive like he did with Amane) then without even waiting three months he started to like Rena. There's just something seriosly wrong here, wasn't Neenee that main female character? So why do I feel like Rena who was supposed to be side character just replaced her? Rena just can't compare with Neenee, she sucks.
I got a feeling that in the end Riku would end up marrying Rena and god knows what happens to Neenee. Probaly gets killed by Riku. I think the author needs to rethink about his plot.
Personally i thought Riku and Rena was obvious from the start. It seem like that was the authors plan to me Neene was a MAJOR character to the story but not the heroine. Honestly i think the direction the author is going is good but at the same time he can easily mess it up as well.
I think it would have been more interesting if the story revolves around Riku and Neenee, with Neenee as the heroine. She would have been a much better heroine than Rena, after all she is more popular with the readers.
