Takuya and Rika have been co-workers at a travel agency but they barely know each other because they are introverts. However one day the management announces a plan to open up a new branch in Alaska, which requires someone to move over, preferably someone unmarried, so they can you know, stay there for a long time. As a result our protagonists decide to conspire in a fake marriage act to doge this responsibility, thinking nobody will pay attention to their marital status anyway. Obviously, something goes wrong, everybody is interested, they have to do way more than expected to put up a convincing show, and obviously they find real feelings along the way.
I would like to start by drawing attention to one minor spoilers as proof that this show is competently written, the choice of the travel agency as the setting in this show is not random, it ties strongly to many resolutions later in the show, which I encourage you to watch and find out.
The star of this show is certainly Hayami Saori, at least I was drawn in because of her, she plays the introvert rumbling of Rika perfectly, making her one of the most charming introvert waifu, despite what I would say is somewhat unbelievable of a hobby they've given her. Rika is a map nerd, she reads maps in her free time, I don't really buy that but it has another more significant role to play *wink travel agency *wink. While both protagonists are introverts, they are still distinct characters, Rika is proactive, she comes up with the fake marriage idea, she will do things on her own accord but she is fearful of emotional investment due to her pas experiences.
Takuya on the other hand is an introvert you've probably seen in shounen shows, he's passive and won't ask the girl out, but unlike inferior shows, Takuya and Rika never recycles the same personality flaw, they learn from each missed opportunity and grow from them. Each challenge faced by our partner in crime is different, and that's the greatest strength of this story.
The Japanese language has this unique characteristic of the Keigo, that is specific words and conjugations you would use to express politeness, usually to people you don't know well, like between coworkers. You probably already know for example you call someone by their last name if they're distant, but by their first name if they're close. Takuya and Rika are often talking in Keigo while discussing things like moving into the same apartment to make their fake marriage more convincing, this kind of detail goes beyond the subtitles but is another fun aspect of the show, the awkwardness and absurdity between two introvert coworkers, I also loved that.
We have some episodes about other coworkers in the travel agency, to explore interesting questions about marriage, which is very much appreciated. However one of these characters, they're even on the poster and looks like an important character, doesn't actually do anything, so I ended up questioning what was the point of their existence. There is also the issue of mediocre production quality, some scenes have questionable anatomy, some scenes that should obviously be animated just inexplicably get still frames instead. It overall looks acceptable but underwhelming.

This story is a thesis on the question of, why get married when you can work and live by yourself? Why risk all the unpleasantness and potential for total failure when you can live in the certainty of a salaryman in modern society? And I like what it had to say in response.
