The story of an abusive boy called Shoei (Jinnai - family name), mostly called Prince, his target girl Mio and their journey through a ridiculous environment of stupid men/boys and stupid events with smut thrown in every now and then.
Honestly every male in this manga has issues that make them arses, the only half decent guy in there is a pimp. >.>
Which left me, as reader, with only the females, and there's only Mio and few side characters as her mother and some maids which can be ignored since their presence is too insignificant.
I found Mio a likable character, who has at least common sense and a nice personality but is weak and gives in easily. Another flaw is that she's easy to arouse and thus falls for the "Prince" who treats her often poorly. But after all it's a smut manga. But it wasn't worth reading for the smut part either.
If you want smut read the Forbidden Love Mangas (#1: Kindan no Koi wo Shiyou, #2: Zoku - Kindan no Koi wo Shiyou, #3: Kindan no Koi de Ikou - cliché but likable) or if you want drama on top try Hapi Mari - it's labeled Josei but its content is more Shoujo.
Now back to Desire Climax - The events and story are like from a bad soap opera*. It's even for a Shoujo too much. If at least the main male would be likable but I really wished Mio would just kick is head and run for it. Sayonara my Prince.
I only finished it because it was on my reading list.
*Spoiler:
We have kidnapping in childhood there which is of course forgotten and remembered later. After they fall in love it turns out Mio is the half-sister of Shoei. Just to have it later turn out - after they had sex - that it isn't her but her brother who is the unrelated one to her family and the half-brother of Shoei.
The gardener suddenly reveals his hatred and his scheming to take down the Jinnai family. As he is the son of the man who kidnapped Mio in her childhood and did a suicide afterwards. Daddy died and the Jinnais took the boy in who later wants to destroy the family... no words, honestly what a stupid turn of events.
The brother, now not-brother, makes harassing moves towards his "sister" (eeeh) and sees Shoei as his rival but the one who suffers is always Mio. The father of Shoei and the half-brother, whose name I've forgotten despite I just finished the manga last night, lol, well the father seems to be nice but he ignores a lot even when he knows most stuff and lets things just happen, what a shitty parent.
Then there's the glasses fetish... almost like Horatio from CSI Miami... glasses on, glasses off, glasses on, glasses off etc.
If you want to know the end. Well mom comes out of the hospital, of course this is made as a dramatic story element as well. She wants Mio out of this environment and moves with her and the not-brother far away. Well, since Mio is now totally in love with Shoei it is too late for such actions. Shoei follows her. End.
