TIKB-110 — Balls Empty Friday Riritan Hyoudou Riria

A week for an office worker: [Monday] Somehow making it to work; [Tuesday] Still unable to return to society; [Wednesday] Telling yourself that you're at the halfway point of the week; [Thursday] Getting seriously scolded by your boss; [Friday] Mysteriously becoming invincible. That's what a Friday is like for these middle-aged office workers with empty balls.
