This manga hits a lot of bad spots for me: age-gap (both are adults, to be clear), sex being used as a transaction, sex while under the influence of alcohol, and generally the method the younger guy uses to get close to the older guy. So, that's my explanation for the score I gave it. Still, the mystery aspect is very compelling. Who is this younger guy? What is his connection to the older guy's childhood friend? What does he know about the older guy's past? And I think the answers make sense and are satisfying (except there probably is a way to work around theage-gap). The way the characters are able to learn from each other and find comfort in each other was also nice. Characters should grow through their relationships, and this manga does just that. So, I'd say the story is well-written.

The art is very nice. Makes the read much more pleasant.
