Hi! I'm looking for a manga I read around 2016. In it, the main character is a high school girl who falls in love and starts dating her classmate. However, she starts experiencing strange symptoms like being unable to feel her legs and ultimately gets diagnosed with ALS. Does anyone know what it's called?

full disclaimer I haven't read this but I did a quick google search and found a reddit post that matches this description? the manga they mentioned was 10-manbun no 1

yes that's the one!
