Don't misunderstand the medium score I gave this; I wholeheartedly enjoyed it. It's quite entertaining, but the problem is that I can't really justify calling it "good".
The plot revolves around a pair of highschoolers who share a love for each other that neither feels is appropriate given their circumstances. One night they both make a wish that their rooms would be joined together, and a deity known as the Obverse God grants their wish, but with the caveat that the girl will lose all sense of self-control for a full hour every day. Romantic and familial drama ensue, riddled with teenage hormones.
Story: Honestly this is the weakest part, and I kind of have a hard time even giving it a 5 out of 10. There's less plot here than most romance stories have, and honestly less story than some actual Hentai have. They love each other, her family gets in the way, they 'do their best' to overcome it (largely off-screen)... that's basically it. If you take out the sexy scenes, there's maybe 2 chapters worth of actual content here, and it would be a totally bland and by-the-books 'nobility' romance. That said, I do have to give it props for purusing an actual story rather than just stringing a bunch of H-scenes together and calling it a day. There's a clear starting point and ending point with dramatic and emotional tension at the climax that concludes the issue and leaves the characters in a different place than when they began, so by all rights it checks the boxes for 'being a story'. And again I'd like to clarify that despite my grievances with the story, I did enjoy reading it and I was quite happy with how it ended.
Art: Easily the best part about this manga. Gorgeous detail in every panel, in both foreground and background. Everything is done nicely and cleanly. Probably some of the best art you'll find in this genre. There's very little wasted space or plain backgrounds, everything is properly proportioned and stays in its panel frames appropriately. When things get exciting and the action picks up, the typical 'action lines' and squiggly textboxes that comes staple with manga are properly subdued - clear and present, but not obstructing the ability to understand or see what's going on.
Characters: Surprisingly above-par for a work of this genre. The main characters feel like they have genuine motivation, and are given enough background to be believable. Their actions are clearly guided by their established personalities, and so nothing they do feels out-of-character. Both of the main characters are also quite robust in terms of unique traits and quirks that make them feel more human. The only weak part of the characterization in this one is the side-characters. We see the father, the sister, and a few other side-characters who have prominent interactions with the MCs and the story, but they're all pretty one-dimensional characters that basically just serve to thrust drama and development upon the MCs without doing anything interesting themselves. I would have really like to see more characterization here.
Overall: A really enjoyable, if simple, romance that's well worth the read. I thoroughly enjoyed it, but I wouldn't really give it any special awards.
Note on tags: This absolutely deserves the Borderline H and Explicit Sex tags. The MCs are quite often and quite clearly engaged in a wide variety of sexual situations, with as little censorship as the artist could get away with.
