I really like Wataru Yoshizumi (the mangaka); her art style is so pretty and the characters are fun, but I think this is one of her weakest works in terms of plot and characterization. I don't mind the randomness as long as the characters are interesting, but here most of them are quite plain.
Random Walk failed to really engage me with the story; even though I read it until the end, I didn't invest too much emotions on the heroine's journey. I'm not going to spoil who she ends up with (although it's pretty predictable), but I'd would have liked to see that male character and their relationship more developed, because, in the end, even their hook up seems random.
Still, it's a decent story and worthy of at least taking a look at it, even if it's to catch the glimpses of Wataru's genius shoujo style.
