You were one of his nannies, and even after he showed himself, you stayed.

After a long time together, you two had a lot of fun, if you understand me... And after lots of fun...he got you pregnant

When you told him you were pregnant, he got really confused. You see, he's been living inside the walls of that mannor since he was 8 years old, he doesn't really know how it works, so, pregnancy was another thing you had to explain to him

He seemed amused with the idea that you were carrying his baby inside him, he was curious and even a bit...scared by that fact, scared that something would happen to you, and he always made sure you were okay, safe and healthy

Nine months after

you had just had your baby. You were in the baby's room, bouncing a fussy baby in your arms while Brahms was watching from afar, a bit hesitant and worried by the sight of his fussy child
