Koi To Uso, is a romantic slice-of-life anime is adapted from the manga with the same same and identical plotline, based in alternative version of modern Japan, where the Government assigns partners to every child to boost childbirth and combat lower birthrates.
One of the best romantic animes I have every watched - blend of humour and melancholy, grievance and unconditional love, determination to protect the one you love even though you may not be able to live your life with that person, regret and happiness, gains and sacrifice - with good quality sound track, beautiful artistic styles, and of course good music.
"Telling lies to protect someone you love will only destroy you/them in the end" formed the basis of the anime/manga.
The first episode was of huge enjoyment with humour with inclusion of melancholy and being lost in the end of it. As the anime carried on, it brings much more homour, cringeness, some minor explicit scenes, one scene of BL, but in my opinion the anime is mainly melancholic. Humours in the sense that Yukari Nejima is being asked to kiss his crush by his assigned wife, which was cringy as well. But, hey, she only knows romance though reading and watching shows, but never experienced it hence has no idea of the concept of "love". Hence it is alright for her to say this only to find herself a bit annoyed in the end, isn't it?
Only the ending, might have ruined the enjoyment of the story, as it shows a stubborn characters and sacrificial mentality, keen to choose two girls together and what not, which might not be liked by some people, and they could have covered a bit more of the manga to cut off that disappointment. Because, when something ends suddenly like this without you knowing why they have this scene, it will bring out disappointment towards the anime. Once you read the manga and cross this scene and go forward, the context of that incident. The timing and the covering content was bad there.
And yes, I highly recommend to read the manga more than watching the anime, or immediately after watching the anime to get a good idea of the story and to cut off the disappointment you might have after watching the anime. It is super-recommended to read the manga. IF YOU ARE DISAPPOINTED OF THE ENDING, PLEASE READ THE MANGA!! Chapters after the chapters covered in the anime, the manga is mostly melancholic and reading it, you will get very emotional. Sadness, grievance, sacrifice for the person you love and lying to that person to protect him formed the basis of the rest of the manga with little humour to hold on the readers' interest.
Overall, rating this 8/10
Opinion: I honestly have no idea why they are not bringing a second season. The storyline covered in the first season might look a bit disappointing, as usual that some manga have some disappointing scenes at the start and as we go on it gets really beautiful. What happens next is wayyy more interesting and beautiful and lovely, and bringing season 2 with the perfect timings and coverings of the manga will easily collect higher ratings. I would honestly love a second season of this.
