The depressed version of "Restaurant of the Awkward People"
Certainly the first thing this reminded me of. With the second chapter also bringing a dose of "The Guy She Was Interested in Wasn't a Guy At All".
Ngl, the 2nd and 3rd chapters made me idly fantasize about how this plot could very easily take a "The Guy She Was Interested in Wasn't a Guy At All" direction. For example, if the OL decided to reassume her rocker persona when she's not at work and in that way interact more eagerly with the café girl.
Also, note to uploaders - the second chapter's download also includes the first chapter both as a separate folder and a zip file. Might be a good idea to fix this.
Always glad to meet more people who also like to dl and save the stories they like.
