One of the main reasons why I like this show is because it does exactly what people want to see out of a drama-romance anime; with it's short length (only 6 episodes), it forces the story forward without much in the way of pointless filler or storylines that don't correlate with the main narrative. This gives it great pacing in my opinion with the constraints given. However this was also a negative for me; the main story they chose to focus on was one about a character who was connected to both protagonists and impacted them personally in some way. This left it feeling like the anime wasn't about the main couple but rather about this character and how they deal with revelations about them that leave them wrapped up in doubt and frustration. And with the short amount of episodes, the anime couldn't further explore the couple's story beyond that.
That being said, the anime does have a conclusive ending that was the one everyone was waiting to see, and it felt very gratifying. It also has superb animation and attractive character designs that are incredibly pleasing to look at, as well as a top-tier soundtrack. For a show that felt more like an OVA than a full series, it was a pleasant surprise. The two main characters, Haruki and Miou, were both likeable and had unique traits about them which made them stand out from usual romance protagonists as well as being very cute with each other. The anime also focuses on two side couples which are also likeable and enjoyable to see develop and eventually receive a conclusion.
Itsudatte Bokura no Koi wa 10 cm Datta is a short and sweet little romance series that I think a lot of people have missed, and I think it's exactly what lovers of romance/shoujo anime are looking for. It does all the usual conventions of a love drama in a visually appealing and entertaining fashion but doesn't have much in the way of content, as it remains only 6 episodes long. While it is a cute love story that I overall recommend, in the end it did leave a little more to be desired.
