Namida Usagi in short you could say is a kind of bad copy of Ao Haru Ride.
SIMILARITIES WITH SPOILERS
In both stories the main characters meet and fall in love in middle school, but their romance doesn't begin because the male protagonist suddenly moves away.
The two protagonists meet again in the same high school but something is changed in the male protagonist and for this reason they are unable to start their relationship.
Despite it's clear that they both are still in love, they will have to overcome numerous obstacles before getting together.
One of the obstacles they have in common is that the male protagonist at first rejects the female protagonist's confession because, even if he loves her, at that moment of her confession he is chained in a toxic relationship with a childhood friend of his.
Ao Haru Ride is better written (both the story and the characters) than Namida Usagi.
In a certain sense Ao Haru Ride is what the reader would have expected to read in Namida Usagi.
ART
The drawings of this manga seem like a bad imitation of Arina Tanemura's drawings (this was to be expected because the author of this manga was an assistant of Arina Tanemura in the past)
5/10
CHARACTERS
The characters are flat and stereotyped. They often say or do ridiculous things.
I expect something like this if I read a manga like Sensei Kushu which tries to make a deliberate comedy out of these facts or dialogues, but in this manga they take themselves seriously and this makes them quite cringe.
In fact, reading this manga is often embrassing.
An honorable mention goes to the protagonist's best friend and her boyfriend, who are the stupidest and most insufferable supporting characters I've ever found in a shoujo manga.
5/10
STORY
The first volumes (especially the first) are nice, but the further the story goes the more boring and embarrassing it becomes.
I recommend you read the first volumes and then stop reading when the two main protagonists get together.
The subsequent volumes lengthen the plot without having substance.

CONCLUSION
In conclusion, I recommend this manga ONLY to those who are VERY YOUNG (this fact mostly due to the immaturity of the dialogues and actions of the main and non-main characters) and who have LITTLE EXPERIENCE reading shoujo manga.
It's not the best shoujo manga you'll find around, but if you're new to it and if you are looking for a nice romantic light read, this shoujo manga will probably be right for you.
However, if I can be honest, I recommend you read Ao Haru Ride instead of Namida Usagi (or read both) since Ao Haru Ride, if it were focused on photography, would objectively be the improved version of this shoujo manga.
