Okitegami Kyoko no Biboroku (2015)

Similar plot but in the drama ML is the one who forget in the movie is FL. Yamazaki Kento & Kawaguchi Haruna stars in this movie. I really recommended this movie coz I like the genre & is worth watching.

Both deal with a male lead trying to get close to the female lead although her memory resets after a set time. In "One Week Friends" the time period is a week, in "Okitegami ...", the lead's memory resets every time she wakes up. Plus, in Okitegami she's a detective.

the chemistry between the main character and how they solved the case
i put this because when i watch sakurako-san i felt kinda similiar feel? like when i watch okitegami kyoko? and like what i said earlier, the chemistry between the character is really good either sakurako san or okitegami kyoko
sorry if my english bad ^^

There is a similar relationship between male and female leads.
The main characters have unusual characteristics.
Both groups of main characters feel like a family.

FL has the same syndrome, her memory reset when she slept. She wrote her diary in her body instead. Albeit minimal romance

By the same screenwriter. They both are mysteries that are handling unsolved cases or deaths. You learn to love each character as they solve each case leading to the main case of the main lead or the side characters.

both deal wtih amnesia with it's like to be a friend/love someone memory resets when they fall asleep.

okitegami is a detective comedy with light romance if you are in the mood for something with the same theme but a quite different tone.

Both are mysteries. Both female leads are detectives and solve the mystery crimes. Each female leads has something unique about them. Kyoko forgers after sleeping and kiina has a great memory and could read super fast. She also love sweets!

I find that most japanese series with female detective are similar in a way that it enjoyable with the way they solve the mysteries. Even though Kyoko doesn’t have sisters to help her as a team, her team consist of a maid cafe worker, cafe owner and a young boy. The four sisters works as a team to solve mystery but mostly the younger sister who solves most of the cases.
