Noroware Reijou wa Seinaru Koushaku to Hangyaku suru

Eh, just read this somewhere else, wouldn't recommend it. You'll get like 23 adequate chapters, and then I'm pretty sure either it got axed or the author got bored of it, because the story speedruns introducing the villain, defeating the villain, tying up a couple loose ends, and jumping ahead to when they have a kid, all in 2 chapters
