Some headcanons about Narcissa being Harry's mother-in-law
She loves to show him any of the photos that she made when Draco was a little boy.
And Harry being absolutely fascinated by his husband who looked so innocent and pure as a child.
Of course, Draco is entirely embarrassed and pretends to hate these particular exhibition evenings.
Harry, who cannot wait to see the next album together, in which Draco sleeps in the crib, plays with plush animals or runs without a diaper in the garden.
And the rest of the photos where Draco is plainly cheerful and carefree boy.
Draco advises Narcissa about the best gift for Harry’s birthday or for Christmas.
And Harry being so astonished when during the dinner he not only gets a wonderful cake but also a minor package from his mother-in-law.
'I thought you would love it’ she says blushing a little and gives him a small kiss on the cheek. 'Happy birthday, baby boy.'
When it turns out that he got from her signet with the Malfoy coat of arms, he’s immediately in tears.
Of course, he has the wedding ring, but this is different. This means he belongs to the family.
Harry hugs her tight too moved to say a word.
Harry doesn’t want to live at Grimmauld Place so until they find something suitable, meeting the criteria of both, Draco and Harry live in The Manor.
Narcissa being emotional about it and cries, when they have to move out. She loved to have Harry and Draco nearby.
And then it turns out that Harry bought huge property not far away from Malfoy’s Manor only to be in frequent contact with his mother-in-law.
Narcissa cries again, but with joy.
Harry who goes shopping with Narcissa and carries all purchases, even if he bearly handles.
At their wedding, Narcissa orating the most beautiful speech about how the two souls eventually merge into one and how glad she is to have a second son in the family.
And it made Harry almost choke on tears.
He loves to send her flowers and always remembers about Women’s Day, her birthday and the day when she saved him from being captured by Voldemort.
Once they went to her for afternoon tea. She prepared everything in the garden and when they were all seated Harry started a very important conversation.
'I received a letter recently. From McGonagall. She offers me Defense Against the Dark Arts position at Hogwarts.’
And Draco looks as surprised as his mother.
'Why didn’t you tell me?’ he asks calmly, but with a little reproach.
'I wanted to discuss it together’ says Harry.
'And would you like to be a teacher, sweetheart?’ Narcissa asks mildly.
'Of course I do. It would be fabulous’ he claims.
'Well then, I think it’s fixed already’ says Draco with a little smirk on his face.
But Harry waits for Narcissa’s opinion. Her judgment is as important to him as his husband’s judgment.
'You know what I think, Harry. I want you both to be happy, nothing more.’
'And that won’t bother you, that your son-in-law is a teacher, mom?’
Draco and Narcissa are speechless.
'What did you just said?’ she whispers and it’s bearly audible. Harry doesn’t know what’s going on.
'I-I…’ he didn’t finish, because she already had him in her arms.
'Of course I did. She is my mom.’
