Firstly, this is very much a slice of life show. If you're not a big fan of those, you may not want to watch this one. I enjoy slice of life, romance, comedy, fantasy, sci-fi, and other light-sided genre, so it appealed to me.
This show also incorporates a fantasy element - a magic library. I won't go into a lot of detail, so as not to ruin the story, but this library (while only briefly and periodically mentioned) is a theme that is important to every character in the show (but two, specifically). Your Main Character, Kakei, is seen having premonitions right from the get-go. He has this strange, but imperfected, ability - which he uses mostly to save people. The First girl he saves using it (Shirasaki) was distributing flyers to start a club with the unspecific goal of 'making people happy' at the time, and later invites him to join her and her friend. The club grows in size and popularity as the show continues, as does the back story and magic library information.
The characters are pretty fun to watch, their interactions are light-hearted and fluffy, but there are some tensions here and there between some of the side characters and the main characters. There is also the typical 'harem-style' anime theme of 'who does the MC really love?!' going on between the main female characters. The show doesn't have any naughty bits exposed, but there are some brief nudity scenes and some suggestive humor, but it is mostly a clean, happy romantic-style slice of life with little drama. Perfectly suited for sitting back on the couch or bed and relax while watching. You don't have to think too hard to follow the story.
