Oh, so that's what we are doing now? Since he said that he would focus on Rin only she got mad since, after all, all her characters are still Rin, so is she trying to "seduce" him while using all of her characters? Good. I guess that's what you would expect from dating an actress.
Even If I still prefer natural Rin to interact with him without relying on her characters to exagerate some of her qualities, it seems that the use of the harem personas let her be the "leading" part of the relationship so Im ok with it. I love chad senpai but Rin deserves to get the spotlight as well.
