Haikavetham and Dottolone have the same secret ingredient that makes people love them: pushback.
It's the back and forth, the subtle competitiveness, the way both parties can dish it and take it. There's affection in there somewhere but it's covered with layers of history and complications. Both of them have people questioning why they'd hang around each other in the first place.
The difference is; Kaveh and Alhaitham are in a slice of life, second chance story. Their hearts know the truth. It's just a matter of walking through life side-by-side and growing into each other.
Whereas Dottore and Pantalone are attached at the hip through a series of debts and favours. Yet, their relationship is probably more genuine than 90% of what goes on within the Fatui. Their affection for one another seems to grow stronger with every contract and deal.
