Thanks for the chapter.
Do not... DO NOT give your phone to the drunk friend, dude. When (if ever) she'll have the mood, she just could remember that call.
As for now Ozu looks like the only decent man between many of the introduced characters. And its quite implemented that he is not the typical japanese (introducing speach, his straightforwardness, Hara's thought "Does he is an idiot?). But its from the western side of view.
Wondering how native japanese could desribe the nuances of the story... May be extremelly wrong (and i'm very sorry if it offended anyone), but I suppose that cheating and messing around with schoolers could have the roots in japanese set of mind. Yes, the influence of western side of view have chanded and continually changing it more with every year, but... first of all, manga was published in the 2005-2008. Its already means 10 years to the past from now (and they are 23+ at this monent)... and look -- there are friend's jokes about schoolgirls (and if they are serious, that is UNACCEPTABLE, expessialy for the teachers) but mans are damn serious about "you just do dogeza", and two woman side of view "what to do, what to do... he could cheat" from 23s Kaori and more adult Takako's "he is not the type to cheat")... if yes, this is not "he is the decent man", but... "he is STRANGE"...
