First off, the main character is a total G. He doesn't put up with the other girls' BS and constantly keeps a calm, rational mind. Overall, his interactions with the females in the harem are very well-handled and their respective relationships develop organically.
This first season was a pleasant, easy watch. The series starts off as a harem/slice-of-life without any real romance. While this can cause the show to feel a tad slow in the beginning, it's made up for with lots of character development, comedic moments, and fan service. Don't worry if you're feeling starved for romance, the last couple episodes pick up a lot of steam and set up a spicy-looking season 2.
If you're a romcom/slice-of-life enjoyer - this is right up your alley. Even if the genre isn't your favorite, I'd still recommend giving this show a try. Like I mentioned previously, there is a decent amount of fanservice but it doesn't feel too over the top. Some of the gags in the show center on comedic fanservice and make for a good laugh.
Final rating: 8
