the author is Hontoku also known as SERVICE BOY(yes that ONE) but this manga is serialized by Weekly Young Jump which is a seinen magazine published by Shueisha and the official tags are seinen, comedy and slice of life
I just find it funny that Hontoku has been drawing gay porn for YEARS but as soon as they got picked up by a big shot magazine they dropped the "gay shit" so damn fast. They even went as far as deleting everything on their pixiv and all their NSFW art on twitter
