Awesome anime!
When I first saw this anime I was pretty sure that this was your everyday's average harem anime but I guess I was wrong.
The story is great
The deep background of the character is sad, but of course when the main character solves them it's heartwarming sometime it's tearjerking
(BEWARE)
This anime was originally a visual novel, so naturally it was atleast 30 hour's long, but with the anime it can't afford to be that long so it obviously has some pacing issues
(Spoiler Example)
A girl protagonist hates guys. And then by the next episode she doesn't mind being his friend.
If you don't really care about the pacing, you'll probably enjoy it!
