I don't understand why everyone hates Ichika but loves Nino. Everyone hates Ichika because she lied and impersonated Miku, which is bad, but she felt bad afterwards, apologized, and then tried to make up for it. She's also a nice person in general the rest of the time too, helping Miku out both before and after pretending to be her. Nino, however, is a jerk the whole series.
