The official SNSs of Ichifure [note: short for Isshuukan Friends] have started posting short character introductions. I’ll translate the two lead characters’ intros here.
Fujimiya Kaori (Kawaguchi Haruna)
A high school student who loses her memory of friends every week. After transferring to this school during the 3rd term of the first year, she never mixes with others. She’s always alone.
Hase Yuuki (Yamazaki Kento)
He’s attracted to Fujimiya Kaori whom he met during the Spring break of the 1st year of high school. Despite knowing about Kaori’s memory defect, his feelings for her doesn’t change. Every week he vows to become friends with her.
