I just finished reading this manga, after binging it for a few days. Highly recommend this to enjoyers of the romcom genre. Its a slice of life romcom with fantasy aspects, with like all of them being demons in the demon world, but to be honest the world is pretty similar to just Japan(not that that is a bad thing). The main couple is between Beelzebub and Mullin, who is her attendant, but there are also a few other couples and a bunch of recurring characters. Similar to most romcom manga, its pretty episodic(idk if that word works for chapters), so that might be somethingyou enjoy or not. Anyways, this is probably one of the best romcom manga I have read, for a variety of reason. For one, its a lot of fluff, there are no harems or love triangles, and not a lot of drama. So if you want like a really spicy dramatic romance manga, this probably isn't for you. But it is definitely for you if otherwise. The characters are all really likeable, my favorite character is Sam, I don't know why but I love him, but he's a great dude. The couples are all really cute, and the side couples do get quite a bit of focus and aren't completely clouded by the main couple. There isn't a whole lot of story, and there aren't really any "arcs", so I'd say time is basically just measured by the romantic progression of the characters. Well that is basically it, it is a pretty simple manga at its core, so I hope you will read it and enjoy it.
