The latest issue of Jump Next features up and coming manga. New comic "Ooedo Punk", which did get some good reviews online, sports some K-On! style eyes and facial expressions that match up with a still from K-On!.
This might be an all out copy, or it might be subconscious. Whatever it is, don't say "lazy".
Update: As eagle-eyed commenters pointed out, the inspiration seems to be Hyouka, which was done by the studio that did the K-On! anime.
