This new to me mangaka and manga was ordered because I liked the cover art, because of the reviews and because I haven't come across a lot of working place yaoi/boys love manga yet.
There's no huge drama here, just a fairly self-confident gay man falling for a heterosexual guy he meets while on the job. The particular strengths of this book I think were actually the descriptions of the two main characters in their dealings within their respective workplaces, the supportive ladies at Sakaki's workplace - the love of furniture design ^^ (the first interior cover has Sakaki sitting in an Eames chair ^^).
Weakness - I do not understand why Sakaki fell for Okada, especially since he has avoided giving his heart completely since he realised he was gay. Nor how Okada then eventually becomes gay-for-him, which is a particularly weak trick to turn (nor the way he compliments Sakaki on the fragrance he uses, which I rather doubt a male Japanese businessman would do to a business partner, honestly).
What IS nicely done is the way hetero Okada then throws himself into the relationship, worries about himself and all - when he finally decides to accept Sakaki's feelings and explore them completely, because he himself can't get Sakaki off his mind after he has confessed to him. The scenes are awkward and very believable and tender.
Another strength is that the manga shows the victims of this desire, too - Miyama, the guy who was Sakaki's partner and who had hoped for more than just sex for a long time. He's a totally nice character and doesn't deserve how Sakaki has treated him in the slightest.
