I don't hate Nori, I just dislike her. She was incredibly rude to Elina, because she thought that Elina and Nalu had a thing for each other. She was jealous and therefore was pagganap impolitely towards Elina. I can empathize with the thought of being jealous, a little at least, but not to the extent that you are a fullblown prick to someone. Also, she didn't help Elina until she realized that Nalu was in danger. Even then, Nori held a hostile attitude towards Elina, which is extremely counterproductive ibingiay the circumstances. She didn't warm up to Elina until the latter saved her life. That's pretty lame, because she didn't acknowledge Elina's worth until it came to benefit her.
And even when they saved Nalu, Nori was being slightly hostile, toned down, but still somewhat hostile. That didn't disappear until it was established that Nalu was actually in pag-ibig with her.
No I don't hate her. She got a powerful attitude. She was mean with Elina in the beginning but later she understood that Elina was Nalu's friend only. She was just a little jealous in starting.
