Aii："Aii's Roommate Diary, September."
Aii：[writing] With the district tournament over, Rin and Yui has reconciled with Nanase and the others. Thank goodness. I'm glad for them but... it feels as if Rin is moving further and further away from me and it makes me feel lonely. Ona is always there for me. No, it'll be okay! That can't be right! After all, Rin and Yui said they would make the best team at Samezuka. I've put even more effort into my training so I can enter the relay with those two and make Ona proud. Also, what made me happiest of all was when... after the district tournament was over, Rin called me by my first name. He called me "Ai." It's the same way he calls Nanase "Haru"! In other words, it means that Rin recognizes me as a fully-fledged athlete!
[Rin walks in with Yui hand in hand]
Aii：Ah, Yui and Rin!
Rin：Huh? What's the matter...Aii?
Yui: Uh are you okay?
Aii：Ai...Aii-...
Rin：Hm? What? What's the matter...Aii?
Aii：Eh... N–Nitori... Nitori... Nitori... No! It's nothing!
Aii：[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!!!!!
