Finding friends isn’t always that easy, especially in the case of Kaori.
High school is perhaps one of the most insecure stages of your life. As you start to grow, physically and mentally, you roam in a vast web with different people and events. Keeping your cool can be harder than you might think.
It won’t be the first time when a franchise centers around a girl who has memory loss and a guy goes beyond his comfort zone to win over the love of his life. Main girl Kaori gets her memory reset every week and Hase tries to become her friend over and over. With Kaori writing down her events in a diary, their relationship should flourish.
And in some respects it does. Of course the series treats you with a certain amount of setbacks to not give you a complete sense of fulfillment. Which is a shame as the show’s strong point is emphasizing the innocent and friendly relationship between the two main characters.
Isshuukan Friends isn’t overly cute and sugary though. The series gives an honest impression and doesn’t give you the experience you might expect.
I stated earlier that the show tries to build in some less fulfilling moments to regain the severity of the situation. Memory loss isn’t only fun, it can also destroy a lot of things. With these events taking place, the viewer’s appreciation for the happy times grows and creates bonding between the audience and the cast.
The side characters act more as plot devices to progress the story. They guide Hase and Kaori into shaping their friendship. I still find it a shame the series didn’t go the extra mile to really emphasize the possible romantic relationship between Hase and Kaori.
Isshuukan Friends has a colorful visual scheme and this technique gives the show a refreshing water paint feel. The visuals give Isshuukan Friends a more approachable slice of life feel.
The soundtrack doesn’t do anything out of the ordinary, but it nonetheless complements the show.
Isshuukan Friends was the show of spring season 2014 with it’s wonderful, innocent and magical display. The main characters had a great development and completed each other throughout the different events. They acted naturally and fitted neatly in the colorful world. Isshuukan Friends gets a 9 out of 10 and deserves a spot in the top 10 of 2014 already.

Definitely one of the better soothing series of Spring, loved the pace of the animation screenplay as the events were well distributed and not trying too hard to piece together.
One Week Friends was my favorite series of the spring season as well, I just loved the whole experience. The story was sweet yet powerful and the characters were very endearing. I absolutely loved the atmosphere, as the story could hit really hard with the emotions (I remember the cliffhanger of episode 9 was especially awful for me) yet remained consistently optimistic on the whole. 1WF was an absolutely lovely watch for me and I would very much love to see more of it in the future. I’m not sure if any future installments could match the quality of this season, but seeing more of the character interactions would be a treat for me either way.
I doesn’t look like a show that will receive multiple seasons. The story was already quite complete in the anime series. But the authentic look and feel were outstanding.
