I technically started writing one but I lost the plot of what I wanted to do with it. setting that aside and just thinking of revgumi->vampire setting though (since the wip is doing other stuff too), the natural setup is Figaro sires Faust and Leno is livestock, right? I typed that and then immediately after thinking about it decided it actually makes more sense if Faust was turned by some other means and Figaro takes him in to teach him about vampire life after the fact... I don't think Figaro would take the initiative to turn him himself... I think if Faust was originally a human, then turns into a vampire, the shift in his relationship with Alec is interesting... it's a subtle difference, but the turning point of Faust becoming something that feels far away from Alec's reach is much more stark like this, right? I'm sure Alec would still try to support and accept and understand his friend and believe he hadn't changed, but over time, it becomes harder and harder to become unsure and wonder if his nature hasn't really changed...
