"The Daydream potion," Hermione explains. "The person who intakes it experiences very vivid and realistic daydreams of all they could ever want, but is essentially in a severely catatonic state out in the external world, incapable of any basic functions." / "And... the cure?" Ron asks. / "The tears of anyone the experiencer craves love of." — Draco/Harry. Set around & post DH.
