[Warning] This is more of a word vomit than an actual review. I apologize.
Friendships in mainstream shonen anime usually mean having two bros punching and kicking, shedding sweat and blood to prove their bravery, perseverance, strength and physical sacrifice. I came across this manga out of sheer coincidence. In fact, I rarely read any shojo, but I'm glad that I read this one.
The "Secret of Friendship" between Eiko and Moe is nothing less compelling - just perhaps, a hell lot less painful in comparison. It's rare to find a story that centers around a friendship between two young girls, who are so utterly devoted to one another, that they would choose to be with each other any day over their boyfriends. They are self-revealing, accepting and intimate; they wear their hearts on their sleeves for the world to see.
Personally, I found it refreshing and rather touching. It is a pure relationship that is so down-to-earth yet so beyond my comprehension. My cynical little heart felt warm by the time I finished.
