I originally started following this story because I really loved the premise of it: it's a story about ordinary characters and the equally average lives they live. And I loved that this actually even became the moral of the story in the end! However, I think it really fell flat with its romance, which is a shame because there was so much potential! I think the mangaka focused so much on portraying the normality of day-to-day living, that they forgot that the romance could still be special. You don't need fantasy or eroticism to make a romantic relationship entertaining and/or heart-warming, so it really bummed me out that, despite the message of the story promoting ordinary kinda characters, the romance was portrayed as "dull" or "uneventful" BECAUSE they were normal.
If anyone's looking for a manga where the MCs are ordinary characters with average lives, but portrays the romance in an engaging/heart-warming way, check out Futari Ashitamo Sorenarini! In my opinion, the romance in this is what Utakata Dialog COULD have achieved, but unfortunately didn't. Anyways, long post over! Despite my opinion on this manga, thanks for scanlating it fully through!
