Note: The manga seems to be an "ad" for the LN, so keep that in mind.. I wish I knew that beforehand. Otherwise, it is really good!
There are a lot of characters, and they feel pretty human! Yariba is a strong adult male character that appears to be able to handle anything, but he is an interesting and flawed character fighting to be the man people think he is. He is calculating and thinking everything through, even when he falters. This goes well with Karen, a bright-eyed and hopeful teen that is determined to get everything she wants, even when she doesn't understand how hellish that will be. She still moves forward and fights to find her happiness. Every side character is just as complex, even if they aren't a focus for long periods at times. Everyone feels human, something a lot of manga messes up.
The story is... messy, but in a good way. One thing's for sure: it is obvious that this is prose put into manga form. There are two main storylines: the dream and writing story, and the office drama story. It's intriguing watching how these storylines mix and meld with one another, but that makes it feel realistic. I mean when one has drama at home, work doesn't disappear or wait its turn to cause chaos. The pace is fast more often than not because of this, and I can't decide if I recommend taking the manga slow and steady or riding the chaos full speed. I did the latter, and there are some details that I feel I may have missed from doing so... BUT THE DRAMA!
7/10 I really enjoyed it, but I'm not sure I recommend it wholeheartedly. The ending is abrupt and not terribly satisfying, as one would expect from a LN "ad." As far as I found, there is no English translation for the LN readily available either. If you want realistic melodramatic Japanese office drama, I think this is pretty up there. The romance is a lot less than the title would suggest, but the relationship between characters is fantastic.
