Typical shoujo, honestly. It's nothing special, but I like the art a lot - Izumi is just so pretty to look at, regardless of what form s/he's in, and Hikaru is adorable. There isn't much of an ongoing plot thread, and none of the characters really have depths (which is too bad, because we get hints of an interesting history from some of them that are never expanded on), but it's good for a light, easy read. Like others have said, the ending does seem a little abrupt; I kind of got the feeling that the mangaka wasn't sure where the story was going, and she just took the opportunity to end things before she started to get lost.
Going into it, expect the mostly typical shoujo trope of all men being rapists and that being totally okay. The manga basically starts with Izumi stripping Hikaru's unconscious body and taking pictures of her topless, then using said photos to blackmail her. (Hikaru literally sneaks out every night afterwards to sleep elsewhere because she is rightfully terrified of being alone and vulnerable with Izumi.) There's also two different men later on, who after being rejected pursue their respective love interests doggedly, usually with clear intent to sexually assault - not to mention the creepy director who sends his female underlings bikinis to wear to a wrap party. Every time something happens as well, its never shown to be the man's fault - it's the girl's, for being 'too trusting'.
^ Let me just say that this is really typical shoujo fare; it didn't bother me my first few readthroughs, but now that I've read enough really good shoujo, finding this aspect here bothered me a lot, and every time it came up it took me out of the experience of reading it.
All that being said though, I would give this a shot - it's not very long, and you can pretty much tell from the first volume whether this is something you would enjoy reading. Even though this wasn't as great as I'd remembered, I had fun going through this again and basically binged it in one night 🙂
