Yay, my first review ^.^

This manga honestly took me by surprise. I'm not normally a fan of manga or anime like this, but I was surprised to find myself captivated by One Week Friends.

In a nutshell, One Week Friends is the story of a girl named Fujimiya Kaori, who loses all memories of her friends every week, and boy named Hase Yuuki, who decides to make friends with her every week, despite her forgetting all about him over and over.

Looking at that overview, I didn't expect the story to offer much, but boy was I wrong.
The manga kept me rooting for the characters read more

Having read 11 chapters, I have given this manga an overall rating of 8. I have greatly enjoyed reading it and wish a lot more chapters had been released.

PROS: I like the fluffy art-style, I enjoy the story, the characters are cool people, the story progression so far has been good and well paced and its 4koma style fits it well.

CONS: It releases rather slowly (though this is probably the translator's fault) and there are some minor plot holes when dealing with the girl's memory capabilities.

The first chapter is a very good indicator of what the rest of the chapters feel like and read more

Seinen romance where female lead suffers from daily/weekly memory loss. Both female characters must maintain a diary in order to chronicle their life and personal relationships.

They're both by the same mangaka, so they're artwork are very similar. Both have a similar atmosphere between the characters, which make them really lovely; though "Isshuukan Friends." has a more complicated plot than "Kimi to Kami Hikouki to." Both were published before as novels.
