What Nobu meant is that the bullying matter will add some more events in the anime, and it will make it more, let's say, lively and thus it won't get boring and the Main character,as Nobu said, will have the opportunity to "shine".
I wonder which route will they pick next, after finishing Miyako's (I am so excited as to play Miyako's route,she is like 2nd after Wanko, personally XD )
The way things escalate too quickly, mainly showing lack in some VNs' story lines. Can be, as OneManArmy said, Hentai-related or just the characters' actions in need for more explanations (Means there are some VNs that are essentially Hentai-based and thus they ignore the story development).
