Ohayoo! Mina, It's 10:38am as im typing this."Why in the morning"You ask? Because rn i got nothing better to do so lets do this thang.

Well this show does more than give your brain just a bit of a workout on thinking about a “what if” scenario that is rather unusual.

They actually do a rather good job of helping you understand what your life might be like if you had the same affliction.

Just what would it be like for me personally to have a friend that every Monday morning I had to re-introduce myself as if for the first time.

How would it feel read more

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

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. 
reportRecommended by Lazu
Anime: Clannad
School relationships, mystery, and romance are central themes in both. The strange occurrence of memory loss or amnesia is present in both as key plot devices, along with characters whose pasts conceal secrets. The way both male protagonists go to great lengths to help the female characters in respective series with so much effort is very similar. Also the way the main female characters in both are alone and are first approached by the male protagonist and helps them to make friends is very similar.
