My Youth Romantic Comedy Is Wrong, As I Expected @ comic, Vol. 7 (manga) — Wataru Watari

Who thought it would be a good idea to put the biggest, most cynical loner in school on the cultural festival committee? What's done is done, and Hachiman wants nothing more than to work as little as possible. But when the committee chair can't be bothered to even show up, Yukino and the others have to pick up the slack. As the event draws ever closer, will they be ready in time when half the staff is half-assing it?
