My Youth Romantic Comedy is Wrong, As I Expected @ comic, Vol. 7 (manga)

Who thought it would be a good idea to put
the most cynical, anti-social loner in school on the school festival committee?
What's done is done, and Hachiman wants nothing more than to simply muddle
through and do as little work as possible. But when the head of the committee
can't be bothered to even show up to most meetings, work begins to fall heavily
on Yukino and the others. The event date closes in relentlessly but will they
finish the preparations in time when half the committee is slacking
off?
