[ Rin's logic made no sense, since he always assumed that 'senpai' was almost more formal than 'san' but he wouldn't argue with Rin on that, since he did consider Rin one of his senpais anyway. ]
I just didn't want to be improper and call you something so casual. Rin-senpai is fine with me, since you are older than me and taught me to be better at swimming.
[ Rin was totally one of his senpais and Rin probably knew that. ]
Anyway, what sort of breed are you looking for Yamazaki-san? Certain breeds can be quite high maintenance as puppies, you know.
