Well, the way of the coward and each girl gets her own alt ending?
I couldn't find the chapters themselves, but judging by the list there are 15 chapters divided into 43 subchapters, I guess I got it wrong.
In KanoKari, the problem is not Kazuya, but author Mizuhara. The first time he confessed to her back in ~50 chapter, his only fault is that he didn't let her go after rejection but continued to suffer.
