Now dont get me wrong this game is enjoyable and one i did waste hours on to get the achievements for cause I love achievements. But if you plan on playing it and want to go in blind. DON'T. There's some problematic stuff in this game, probably due to the time of its release since that's what was trending with otome games at the time.
So, one of the routes has an age gap. It can feel a little weird as the main character is 17 and the love interest of the route is about 23-24. It's not a terrible route but the mc is still a minor for a good part of the route until she turned 18, so you might find it uncomfortable.
Then another one of the routes has incest. Now yes it's between step-siblings but that's not really better. The love interest is your step brother and frankly I feel like it would have been better if this was just a found family route instead of a romantically inclined route. And the way it's handle is just kinda weird with them knowing they shouldn't date but do anyway, and the step sister and mom know about it and are okay with it.
I've also see people complain about one of the routes because the love intrests is trapped in the body of a child, thankfully it doesn't last long into the good route, but for the bad route it's not that far from the ending. Its due to his curse, but its still weird to think that you're trying to romace a child at the beginning until the reveal comes he's not actually a child. I thought I'd bring that up at very least.
Also one of the love interest has two personalities, and to say it was done poorly is kinda true. I've seen many people complain how it was done, since it's the thing with one side of the character is evil and the other is good. Because they don't really mesh well together, and the route really wasn't focused on said character all that much.
Now to complete the game and get all the achievements you have to get both ending of each route which essentially has you playing the routes twice, because you get a false scene of your choices mattering. If you make to many of the wrong choices you're sent down the bad route no matter what so if you don't know what choices are wrong or right it could make completing the achievements tiresome.
Now with all this said do I adore the game? Yes I enjoyed it, the game was something for me to kill time when I lost my wifi for a week, the routes are actually interesting if you ca get around some of the icky stuff that's inside of them. But once again that's probably there due to the time of this games release, cause for some reason it was just normalized to have it in games at the time.
But no if you want to give the game a try, I'd say go for it. The story is pretty interesting once you start playing. Now there is a preferred route your supposed to play it in, but I played by which character I thought was interesting so.
