Thanks for the translation.
Weird series. I liked how it tried to do something different by introducing the male lead's issues at work as a serious plot element, but in the end that part completely marginalized everything else, which was not so good in my opinion. I think the story would have benefited from a better balance of plot threads.
Then again, if you look at the characters, with perhaps the exception of the male lead, everyone's portrayal was pretty static. The ex-girlfriend, the kouhai with a crush at work, even Karen did not really change that much during the series' events. So I guess the author concentrated on the work-related parts because corporate intrigue let him keep the story moving without being hampered by his apparent inability to evolve the cast.
Of course, the novels might be completely different and my analysis might be way off the mark, but that's the impression I got from the manga, at least.
