Thanks for all the kind words everyone, I really appreciate it. For those asking about when volume 5 will come out, I did a little poking around, but I haven't found an answer. Maybe a better internet detective than me can scrounge it up, but I think there just haven't been any announcements.
@NamelessSoldier Just turned out to be a tiny hernia and some gastritis, no biggie. They definitely felt worse than they are though (;^ω^).
@Skarrmanga Thanks for the suggestion, but it looks like Tonari no Scanlation is still working on it. They did say they just lost their translator though, so maybe I'll throw my hat in the ring. But then again, I already have a ton going on xD, so maybe not. I'll be mulling it over for a while. I hope they find another one soon, at any rate.
@starburst98 I'll add it to my growing list of prospective future projects, but it'll probably be a while.
