As Above, So Below. (гет)

Zuko has everything he could ever wish for. Working as an analyst for the Earth King Enterprise, Zuko has earned his freedom, prestige, and courage - in short, everything, all by himself. Learning that his sister, who has reached university age, will enrol in Ba Sing Se University, Zuko finds himself in an uncertainty, thinking that the bad old days will return. For all they know, maybe old wounds will be healed and they will become brother and sister the way they should have always been. Maybe even more.
