If you decided to watch this because you saw the Romance genre, Marriage in name and synopsis or because you loved The World God Only Knows you are in for a massive disappointment. Main characters of this show are incredibly bland, act more immature than any middle school romance show and genuinely spend less time interacting with each other in a meaningful way than MC interacting with his cat. Even when they have a scene together it is just them freaking out in their inner monologue and completely ignoring the other. Even when the show accidentally creates a romantic atmosphere it usually ends up with one of the Main Characters freaking out and dashing away from the scene without addressing the situation and then acting like it never happened as much as they can.
Even if you tried to ignore the lack of romance in this show and try to watch this for the plot you would end up massively disappointed because everything plot related happens for the sake of blueballing those rare moments of romantic scenes and ends abruptly with a cliffhanger and never gets addressed at all in the future again. One time a side characters actually gets a cute romantic development and then boom they suddenly create an obstacle and move on from that plot just to completely ignore it next day and show that character being the exact same person.
It's a shame how even the worst arcs of TWGOK anime was superior to this show in every way. Made me reconsider my wish to ask for more adult romance shows. I did my best to enjoy this show out of respect for the author but it was just too bleak, too bland, too devoid of anything interesting or fun. Show even openly tells you : "I was thinking marriage was the finish line. But it's really a beginning, isn't it.". So do not expect an interesting story here, we are not even at the start line after all.
