Yesterday, after I talked with Ryuhan and assuming from the way he was acting all familiar with Senpai, I judged the possibility of him being the ex-boyfriend that Tsumen and Gaisen were telling me about.
But after I came home, I recall it was during the evening that I got a text from Kizhashi. Of course, we couldn't talk at school because we weren't that close, apparently.
I knew that I told her to gather intel about Senpai, which she did quite exquisitely. Judging from her clumsy and obnoxious behaviour, I didn't expect her to be this good at this.
So from her, I got to know some useful and also some miscellaneous information about Senpai, like Naoto didn't like wearing nail polish in both arms, so she only wore it on her right arm.
I was a bit concerned about how she even got to know this information. This was such an useless piece of intel at the same time it was impressive too. Maybe she wasn't that bad of a choice after all.
