Super diligent and organized MC gets entangled with the very free-spirited FMC. They influence each other throughout the story and gradually change into better versions of themselves. It's not the most original concept, but the way it got executed was exceptional for me.
The dialogue is strong and lean, as well as energetically paced. No walls of pointless text to decipher. A very easy and pleasant read.
The art is par, nothing too special, but still better than average.
The characters aren't too interesting except for the two main ones.
The story itself was engaging. Humor is smarter than average and doesn't go for the typical cheap manga antics. Unfortunately, the ending was really, REALLY tepid and possibly the weakest part of the whole story. I'm not sure if it was rushed. It's possible that the mangaka intended it to be this open-ended, but if he did, it was a really weak way to go about it. Yeah, that's pretty much the word that stands out to me when describing the ending. Weak. To be clear, it's not necessarily bad. Just weak and clearly should have been done better.
Overall, I'd still recommend it. It's just that it feels like taking a leisurely ride along the sea and then the whole trip ends in a ramshack hotel nowhere near the beach. But the drive is still good.
