I was standing outside the library entrance. I could see there were a few students inside the library, but the corridor outside was really quiet as school hours ended.
I was reminiscing about my exchange with Gaisen regarding the Kizhashi matter. He seemed to be really carefree about this. Even when I was manipulating him, Tsūmen was more worried than him. It makes little sense, unless Gaisen already has resolved this issue.
Also, when I said about Kizhashi cheating on him, he seemed to be sad about it but it seemed forced to me. Either I'm overthinking things or their relationship isn't working out between them.
Maybe this whole incident was planned by Kizhashi and Haruka as a getaway to break up with their respective partners. This explains why Haruka invited Kizhashi even though he knew Gaisen would probably be busy.
