Ok so, what to say? First of all, you all don't be fooled by the first story, it's really light and heart-warming unlike the others, you can say is a good start.
Then ok, now we start the real deal, 25 years of confinement, I usually put a low score immediately as I see a Rape scene, but I couldn't this time, the reason is pretty much obvious too, the reason for the one being violated to love their aggressor after was explicitly said as Stockholm Syndrome, it has a reason it wasn't 'romanticized', at first I was already upset with the flow of the things, after you learn about the aggressor past you know why he's doing this, simply it's because of revenge. Of course things don't go well, but you can say it does have a happy ending. (We never discovered if the aggressor was arrested or not though). Seeing both characters falling in love with their own aggressors wasn't beautiful or pretty (+points because it shows that rape HURTS, it's not pleasurable like some mangakas write) it is disturbing and sad for them, but they can't help it. I couldn't let myself give this a low score because it was a beautiful story, disturbing and terrorizing, I can't tell anything more about it.
The last story I had to read twice so I could understand everything, well you can say it's another revenge story, yes with rape again, but again the main character didn't enjoy it, not a little bit (SPOILER: he even try suicide once, unsuccessful though), but again after you learn more about the 'bad guy' you discover the why, and you kinda agree with him, since it was his own past-request to do it like this (you only will understand this if you read the story, sorry) anyway, the plot-twist was something I wasn't expecting, and the way the mangaka put the situation was beautiful (you know, with all that 'seats in the heaven's thing, for me this was so beautiful written I couldn't stand not mentioning this), the ending was really satisfying too.
I talked TOO much, but anyway, I recommend to give it a try, you will feel conflicted, but at least I enjoyed reading it.
