Warning: Review contains spoilers.
Just a heads-up so you no what you are getting here.
There are four one-shots, all about waiters at the same cafe, and all told from the perspective of the girls who eventually fall for one of them.
The first three are typical josei/shoujo smut stuff: guy is a little sexually aggressive and a bit stand-offish, but ultimately the cute girl breaks through his cold heart to start a relationship of mutual love.
The last one is no-holds barred NTR--the shoujo version of a bad hentai:
Girl has great relationship with her boyfriend. His twin brother (the waiter) rapes her. (And no, it's not an unclear "was it consensual or not": he sets out to rape her, she tells him no, he rapes her, afterwards he blackmails her to keep it a secret, and he refers to the incident later as a rape). She feels violated and guilty.... but comes back for more anyway. At the end, she is forced to choose between the brothers... and lets just say she chooses poorly.
Except for that last story, the manga is pretty good--if you are looking for josei smut, at least. But be warned about chapter 4. read more
