It kind of is a harem game if you want it to be, and there are a few stories. Besides the main one of finding what happened to MC's dad.I enjoyed the game. Lots of different love interests to pursue. You can skip any you don't want to mess with. There is a story, however most of the game revolves around dating characters and getting to know them. There is some cross over with certain characters and even some 3somes etc.
If you just want to have fun with some interesting characters... then I would recommend this.
If you are looking for a deeps story or a harem game, this is not really that type of game. But I feel still worth the download.
