Blue Period 3 by Tsubasa Yamaguchi

Winner of the 2020 Manga Taisho Grand Prize! A manga about the struggles and rewards of a life dedicated to art. Popular guy Yatora realizes he’s just going through the motions to make other people happy and finds himself in a new passion: painting. But untethering yourself from all your past expectations is dangerous as well as thrilling…

ADAPTATION
 
Relief is short-lived for Yatora after his first competition, where his piece ranks higher than expected but is far from his dream school’s standards. He’s prepared to give Ooba-sensei’s challenges everything he’s got…but what if all he’s got is still not enough? With 100 days until university exams, Yatora must toil to produce a piece only he can.
