...Hmm, I must say, I quite respect the husband, in a sense.
Like, he managed to get himself a wife like her...But not many go the extra mile to ensure their marriage stays happy? Or rather, to keep his wife safe from other men.
And he doesn't even make a fuss about it in public or disturb her daily activities, he just keeps an eye on her and...lets her know of his 'concerns' when she comes home. 'Disciplinary sex', though? That's an interesting way to put it.
That ending though! Well...Looks like she's going to need to be...'punished' more before she finally gets the message, eh?
Husbando-kun (I think that's the appropriate term) seems to be wrestling with a bit of insecurity there ... from what we've seen, even though Saori-san seems to exude sensuality "24-7", she's shown no sign of interest in any other male.
For all we know, this could be a case of 'Art Imitating Life', where "... the names have been changed to protect the innocent."
