There's not much to talk about this OVA, because it doesn't really explore what we were introduced to.
Well, in the synopsis it says that the protagonist starts to become aware of liking the opposite sex, but this was never mentioned in the OVA in a clear way, it was not explored.
There is also kind of a romance that is left very open between the protagonist and his childhood friend, Konami. And guess what? It is not explored either.
The protagonist's friend, Osamu, is always after a girlfriend, but never gets one. In the first episode it is hinted that he might have a relationship with Shino, because they are always arguing. This, too, is not worked out.
The characters themselves are not bad, but the plot does not help to have that much attachment for them.
The character design is very good, it's what I praise the most in this anime. And I also love those anime designs from the 2000s.
The work ignores a lot of things, to in the end have a message of living in the now, because good memories are important. Well, that would be good if it explored the things that we were introduced to.
It's an average anime, it's okay to watch. But as a whole, it's a potential that was wasted.
