This has been one of my favorite manga series for years. I come back and reread it every now and again.
The main selling point of this manga is the absurdist humor. If you're into that, you'll love it. If you're not, then it probably doesn't have much to offer you. The romance is light and there isn't a lot of character growth other than the MC growing out of his delinquent phase. There is a story, and there is story progression, but it tends to be driven by chaos.
The ending is satisfying, but it comes out of the blue. You're just reading along and then bam, it's the last chapter. It makes me wonder if the manga was axed. There aren't any loose threads left though, so maybe the author just ran out of things to say.
