Sixteen-year-old Yuuki Hase finally finds the courage to speak to his crush and ask her if she wants to become friends. The object of his affection, Kaori Fujimiya, is a quiet and reserved girl who cuts herself off from everyone and does not spare him the same blunt rejection she gives everybody else.

Some time after, Yuuki finds her eating lunch on the roof where she secludes herself during break. He decides to start meeting with Kaori every day in the hopes of beginning to understand her better. The more time they spend together, the more she begins to open up to him. However, nearing the end of the week, she starts to push him away once more. It is then revealed to him the reason for Kaori's cold front: at the end of the week, her memories of those close to her, excluding her family, are forgotten, as they are reset every Monday. The result of an accident in middle school, the once popular and kind Kaori is now unable to make friends in fear of hurting the people dear to her.

Determined to become more than just one week friends, Yuuki asks her the exact same question each Monday: "Would you like to be friends?" Because he knows that deep down, Kaori wishes for that more than anything.

One Week Friends is a nice little slice-of-life anime that came out in the Spring season of 2014 and was animated by Brain's Base, who have done a great job on this project. Coming in twelve episodes, it's a quick and easy watch if you're looking for something to spend an evening with a relaxing show.

Story (8/10)
Yuki Hase expresses interest in becoming friends with quiet recluse Kaori Yumijira, who has a reputation for being cold and distant from all the other students inside her class. Initially rejected, he pushes forward and learns of an issue that she has, where every Monday, her memory ...

Mixed Feelings
I think that neither beginning nor the end are important as long as the middle part is good.

Unfortunately it wasn't so good for "One Week Friends"

What really destroyed this anime is pointles amount of filler episodes that bring nothing interesting to the plot, really, episodes are like watching the same tv movie etc. Another downside of OWF is that character development is dead, yes it is, Fujimaya loosess her memory in the end and she remembers nothing, main character is in friendzone (as he was throughout the series)

Damn, I don't want to waste any more time on this crap.

6/10, only because of few ...

Bro what the fuck, where’s the rest of show? It had a great premise and I was really enjoying it but then it just fucking stopped. Nothing got explained, nothing got resolved, it just… ended. Like it said fuck you, go read the manga. It was a goddamn teaser trailer not a fucking tv show. Man this could have been a 6 or even 7/10 if they just fucking finished the show. Goddamn. I looked up the manga and it litereally doesn’t have that many chapters, just fucking finish it you goddamn cowards. Fuck, I hate that shit. You had such a good premise and ...
