Translation
Nitori ：“Nitori’s Roommate Diary, September.”

Nitori ：[writing] With the district tournament over, Rin-senpai has reconciled with Nanase-senpai and the others. Thank goodness.

…I’m glad for him, but… it feels as if Rin-senpai is moving further and further away from me and it makes me feel lonely. No, it’ll be okay! That can’t be right! After all, Rin-senpai said he would make the best team at Samezuka. I’ve put even more effort into my training so I can enter the relay with him. Also, what made me happiest of all was when… after the district tournament was over, Rin-senpai called me by my first name. He called me “Ai.” It’s the same way he calls Nanase-senpai “Haru”! In other words, it means that Senpai recognizes me as a fully-fledged athlete!

[Rin walks in] Nitori ：Ah, Senpai! Rin ：Huh? What’s the matter… Nitori? Nitori ：Ni… Ni–Nitori… Rin ：Hm? What? What’s the matter… Nitori? Nitori ：Eh… N–Nitori… Nitori… Nitori… No! It’s nothing!

Nitori ：[writing] It’s okay if he doesn’t call me that all the time. It’s because he only calls me that some of the time that the happiness when he does call me that increases!!!!!
