One Week Friends

In this German-published manga adaptation of the popular light novel and anime, high schooler Yuki Hase befriends the reserved Kaori Fujimiya, only to discover that every Monday her memories of him—and all her friends—are completely erased. Over the course of seven issues, Yuki patiently rebuilds their friendship week after week, writing in a shared diary to help her remember. Published by Carlsen Comics from 2017 to 2018, this gentle, bittersweet series explores the quiet resilience of connection and the small acts of kindness that can bridge even the most heartbreaking gaps.
