Harry Potter: Do you think I would want to go back to Hogwarts and relive my school days years after graduation? My time is valuable and should be used for greater things! ! !
Gytha Wright: Why did I come back? Without me to deal with the aftermath, his illegitimate children would take over the world in a few years!
Harry Potter: ... My dear, am I as bad as you say?
Gytha Wright: Oh, you had an ex-husband and a love rival in Hogwarts in the 1990s (or so you thought, they didn't know about it)... God knows what impulsive things you would do!
GGxAD, HPxDM will never change, everything else is up to chance~
