So far, I've been pretty impressed by this manga. Let me list some things I like about it.

First, the main female lead isn't annoying. How rare is that?! Often I can't get into mangas because the female lead is too ditsy or annoying, but Fumi does not even annoy me one bit.

Second, I really like the main male lead. He's socially awkward, but a very soft guy inside. The great thing is, he's awkward and never understands things, but he is aware of it and tries to do something about it. So things actually do end up happening.

Third, the side characters are actually supportive and quite likeable. As far as I've read (about chapter 32), there isn't some annoying character that overstays their welcome and keep adding unnecessary drama to the mix. The side characters do their part and move the story along. And even after that we get to see them again; aka they have a good presence in the story but it's not too forced.

Forth, THINGS ACTUALLY PROGRESS. I am actually surprised when it does. I expect that when some trouble comes up, it will take quite some time to resolve, but it moves faster than I expect always. The frustrating feelings from watching the troublesome things are quickly blown away, and that makes the manga great to read.

Finally, back to the main characters again. They are sensible people, and they think about the situation and each other properly. Maybe they'll sulk in a corner like the usual characters in difficult love in shoujo manga, but the difference is that these characters do think about what they want to do - and at surprising times - actually take action. They might do silly things sometimes, but they know it. They apologize. That's amazing.

Overall, I still wouldn't say this manga blows me away or anything. The characters aren't really deep, nor is the story creative and fascinating. It's not particularly special. But if you want a story that isn't frustrating, that's easy to read, that actually progresses, with a likeable cast - give Tsubaki-chou Lonely Planet a try. Sometimes a story doesn't have to have overly complicated plots. But as long as the writing is decent and it doesn't always drag on (looking at you nisekoi), sometimes that's the best of all.

tldr;
if you're looking for something exciting/deep/creative, this isn't really it. But it's definitely easy to read and won't leave you frustrated. It's enjoyable without requiring you to invest too much and feel cheated. Great for people looking for light and easy manga.
