Draco married the younger sister of a fellow Slytherin. Astoria Greengrass, who had gone through a similar (though less violent and frightening) conversion from pure-blood ideals to a more tolerant life view, was felt by Narcissa and Lucius to be something of a disappointment as a daughter-in-law. They had had high hopes of a girl whose family featured on the ‘Sacred Twenty-Eight’, but as Astoria refused to raise their grandson Scorpius in the belief that Muggles were scum, family gatherings were often fraught with tension.

What did Draco Malfoy do as an adult? He had a lot of inherited wealth and didn't need to work but surely he must do something right? His father worked in the ministry and was a part time death eater after all.

Draco works at the Ministry Of Magic, directly below Hermione, who is Minister of Magic.Draco originally had no job as he inherited Malfoy Manor and all the money but seeing as he wanted to be a better person he applied for a different job as a Auror and then got promoted multiple times to where he now stands.
