I'd say the series is not that bad. I know a lot of people call him dense, but his thought process makes sense. I mean, he doesn't want to get in trouble for most the series. Then, when he realizes he won't get in trouble anymore, he seriously thinks about her as a love interest. The ending is cute, with them finally getting together. I understand why it didn't feature too much of their dating/married life. As the whole point of the series was the journey to said relationship and how they grow together. I do find it weird how decided to date (and marry) someone, who is that much younger, but I digress. Overall, the series is an 8/10. This mangaka can really write and draw masterfully.
