While there are some people who prefer solitude and independence, most people are social by nature, and they desire friends to laugh and struggle with in both the good times and the bad. Good company is invaluable, and thus it is important to distinguish who your true friends are. Genuine friendship should not rely on a relationship that is give and take, but rather a relationship based on mutual respect, trust in one another, and unconditional support. A good friendship takes time to mature and develop into an unbreakable bond, and oftentimes requires that friendship to undergo trials and tribulations. One Week Friends explores this read more

Friendzone: The Anime

The plot of Isshuukan Friends consists of a young boy (Hase) who is in love with a beautiful yet estranged girl (Fujimiya). The girl suffers from a condition in which parts of her memories are erased on a weekly basis, on each Monday. This makes it so that Hase, in order to befriend her, is required to introduce himself to her constantly just to keep up their friendship. It also makes for one of the most frustrating anime to watch; it contains one of the biggest "love that never was".

Isshuukan Friends is structured in a way that every single episode, more or less, read more

“Please be friends with me” – Hase. (every single week)

A show about making friends that can be said in 5 simple words. You might think that could turn into a century old trope but Isshuukan Friends (One Week Friends) does something different. It revolutionizes that very simple idea of making friends to bring about a show that is so much more. Based off the manga of the same name written by Matcha Hazuki, making friends is more than just reaching out and extending your hand.

Taken for granted, Isshuukan Friends has a very simple premise. It’s about making friends. The title itself is also easy read more

A heart-warming and satisfying story centering around true friendship and the subjectivity of memories and all the meanwhile it doesn't get too stifling in the process of the story: Isshuukan Friends. Such a marvelous story that people should give a watch.

Story: Isshuukan Friends is about a girl named Fuijimiya Kaori who has post traumatic stress disorder, and her memories reset every Monday. One day, she meets a boy named Hase Yuuki who wants to be her friend, and the story starts from there. As Fuijmiya continuously forgets who Hase is, Hase tries to keep their friendship alive, or start their friendship anew, again and again read more

Anime: ef: A Tale of Memories.
A boy trying to make friends with a girl who is constantly losing her memories.

Anime: Usagi Drop
Both Usagi and Issuukan have a soft and light feel along with a little melancholy. If you watched one and would like something that also revolves around daily life (simple things), and two people coming together and interacting, and light soft feel with a little sad then I would recommend these as being similar. The differences: In Usagi the main girl and guy are very different ages and in a guardianship relationship, The story mostly takes place at home. In Isshuukan the story mostly takes at school and the girl and guy are peers.

Anime: Kimi ni Todoke
In several ways, I find these two series alike for their tone and atmosphere. They both involve a shy girl who happens to meet with a cheerful guy at school. They become friends through their experiences. And despite their differences, the two get along in unusual ways because of their sharp contrasts. There is decent comedy, drama, and sparkling romance throughout both series. Kimi ni Todoke focuses more on romance as a driving plot while Isshuukan Friends deals with friendship. But nonetheless, they both convey character relationship on realistic levels that are appreciable.

Same atmosphere and animation style. Both series deals with dramatic circumstances in life. 
reportRecommended by Tsukasa-san
Anime: Kimi to Boku.
The atmosphere in both are very, very similar. The shows live from their character interactions, how the main characters get closer to each other and create bonds. Also, both have a similar art style, very light and calming. While Isshuukan Friends is a little more dramatic, you'll definitely love one if you enjoyed the other.

Anime: Kotoura-san
A girl with a supernatural problem that causes her to lose all of her friends transfers into a new school.
A boy who is a bit of an idiot decides to make friends with her.
The girl feels she is a burden and denies him at first, but eventually warms up to the idea.
More friends join later on.
Both are heart-warming stories with cute art styles and cute relationships between the characters.
On the other hand, these slice-of-life/comedies also add quite a bit of drama and sadness that can move you to tears.
Both are basically about a lonely girl who  read more
