These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Genius Bonus: You don't have to be a “genius” exactly, but amongst the random room plans in the ending, there's a golden spiral◊.
Squick: Episode 7 is a tender, romantic story about Watashi's love of Jogasaki's love doll.
They Just Didn't Care: We love you, Funimation, but there isn't really an excuse for the synopsis you've got on your website. The narrator isn't a dropout, and the synopsis also implies that the whole series is a flashback after the narrator meets the matrimony god.
Rewatch Bonus: With its anachronistic storytelling and "rewind" storyline, the show's made for this. Go watch episode 1 after episodes 10 and 11 and feel all the Fridge Brilliance kick in.
Shipping Bed Death: The narrator lampshades this as justification in the finale to wrap up other loose ends as opposed to expounding on the details of his budding relationship with Akashi.
What an Idiot: Narrator, there's a reason Ozu brought you a castella and said it would be ideal to eat it with someone.
