Fly me to the Moon, Vol. 12

Nasa lands a teaching job—at an all-girls school! He’s about to discover his students’ spicy secrets, Tsukasa’s capacity for petty jealousy, and whatever’s going on between online slacker Aya and Ginga, who is definitely not a gangster. But Nasa uncovers something truly unexpected when he happens upon plans for spaceflight. Twelve volumes in, is someone finally going to fly someone to the moon?
