There were way too many references to the uke's "devilish" side. He was a very enjoyable character, but the "devilish" thing sounded almost like a voo doo power, seriously less is more.
Other than this it was a nice romance with adult leads that admit their feeling without unnecessary drama. I disliked the woman that was chasing one of them, maybe the author could have found a better plot device to unite them. What really shines in this story are the two leads and I suppose this is what matters most.

Middle-aged men in BL stories are often portrayed to be excessively hyper and juvenile for the sake of drama or comedy, sacrificing good characterisation and a sense of realism in the process. Fortunately, I think this manga was well-handled enough to maintain a good balance between fictitious elements and relatable traits, creating a down-to-earth but fairly vibrant story to keep the audience entertained with a colourful cast of characters told in a masterfully-skilled narrative. I liked what I read and I think you probably will too.
