In general, I agree with you, but i think it has to do with the Japanese culture. They're really big about socializing with coworkers, especially when it's your supervisor. Has something to do with being respectful and polite i guess, which is really important over there.
As much as I am all for socializing with your coworkers after work, that dude Taguchi (?) was right in pointing out that Waki rather CHOSE to spend time with that chick than his lover. I mean just imagine this, you're already hella busy and that free bits of time you get, you do it by accompanying others ? Come on man, PRIORITIES.
Another point is Taguchi also saying Waki didn't mention about that woman getting drunk until it became an article. In what universe does it make you confident that it won't be found out and misunderstood by your lover ? Isn't she a star ? Doesn't she have a manager to take care of her ? Why of all the people on that crew does it have to be you to go dinner with her and grocery shopping even (╯°Д °)╯╧╧
This is why I really hate guys who loves playing hero for damsels in distress (╬￣皿￣)凸
