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

Manga: Kimi to Kamihikooki to.
Created by the same author, both series adapts a story taking place at a school life setting where relationship and youth is explored. The main male protagonist are kind and there is a lot of emphasis on relationship building. Their story pacing is also considered slow with subtle romance that gradually develops. There is an elegant innocence that readers will feel as they read through both series. Recommended for anyone interested in lighthearted drama.

Manga: Usagi Drop
Usagi Drop and Isshuukan Friends brings strong relationship dynamics as part of its storytelling. The main male and female protagonist shares a relationship that develops over a course of time. There is a familiar feel especially with the slow pacing story and slice of life tone. Each chapter depicts their life as they face new obstacles together.
