I'm sure that you will all agree that the most annoying thing about any harem anime is the perverted characters who tries to hit on everyone/ gets hit on by everyone. Thus, I have more or less given up on the harem genre and steer well clear. However, this anime is like hope at the bottom of Pandora's box.
I really like how the protagonist is not just a decent person for once but he cares so much about everyone around him. All he is ever trying to do is help (leading to a number of misconceptions). The story line is not about him and every other girl falling in love symultaniously but rather, it focuses on the development of a single girl's feelings... before disregarding them for the next. He takes everyone's feelings and attitudes to heart, and is always trying to help.
I most certainly did not expect the ending of this.
Plot: (Warning Spoilers)
As I'm sure you've gathered from the synopsis, the series starts with our protagonist looking for his lost sister and when they find one another there is a girl, our other main character, from the presteious girls highschool with the sister. This makes you think, oh no - here we go again.
There is a merger plan between the girls highschool and the protagonist's co-ed school and our protagonist, his sister and his (not perverted) best friend are enrolled in the experiment.
Our main girl instantly makes the boys feel unwelcome and from there on its tsundre. The character development is mainly centred around her rather than every girl. But then suddenly, about half way through the series the main girl switches. Completely unexpected. The new main girl is also tsundre but more heavily so (if you know what I mean). She loves the protagonist but he doesn't seem to love her back. Instead he is falling for her best friend (who is the only one whom he actually loves).
