My Youth Romantic Comedy Is Wrong, As I Expected, (Light Novel) Vol. 04

Ahh, summer break. No school, no responsibilities, and no friends to pass the time with--until Miss Hiratsuka drafts the Service Club (plus a few normies) into volunteering to supervise an elementary school camping trip. But Hachiman has a knack for sticking to the sidelines and is prepared to survive this awkward outing with as little conflict as possible--until he meets a little girl who's already started down the path of loner-dom herself.
