This was sort of a mixed experience for me. I did find many scenes funny but the show is a bit unsure about the emotions it's aiming for and the conclusion doesn't feel earned given how serious they made certain matters.
First of all I really liked the main character. Her character designs during comedic sequences were hilarious and Takahashi Rie did a great job voicing her. I think friendships between all characters are nice too. The plot of the show is that a wizard comes to this introverted girl and says that she's selected as a test subject to help her in her romance developments. Naturally, this girl retaliates and that too in a hilarious manner. So this show is at its best when it's a romance parody.
Obviously, with a plot about affecting romance in your life using magic, you don't expect it to get emotionally serious since it won't fit at all. But, from time to time it gets serious and that doesn't work since obviously the romance feels forced. And I'm not a fan of love-triangle drama either. And then the final 4 episodes completely changed the tone into some very serious matters, which felt sudden. And though it's good that they explored a few backstories, if you've seen enough animes you have probably seen the same backstories done before. And after they establish these very serious problems, the way they end them doesn't feel very convincing.
