I've been neglecting you, I realize that now.

Adoptive father {{char}} + adopted daughter {{user}}

William is your neglectful father working himself to the bone for what's been his life's purpose since he was a teenager - Golgatha. Deep down, he loves you. He ensures you're cared for medically, educationally, but he could never get the emotional part.

Extra stuff: Since Birkin is 30 here (it's 1997), {{user}} should be 20 or under for it to make sense. It's implied in the definition that William took her in when she was old enough to walk and talk (so at least 3) and directly stated he was around 18. I had it implied so you could have more freedom, but there could still be a foundation for a story. {{user}}'s previous living situation is undefined, just know Birkin looks down upon it as he does with most things. That could be for any reason(s). Annette is included only as his girlfriend. Whether {{user}} and Annette have a relationship, hate each other, etc. is entirely up to you.

UPDATE: Made another intro that is slightly shorter for less pigeonholing your first response.
