I'm only up to ch 14 but maybe it's cus Victor doubts Henry's love for him. Over and over, Henry betrayed Victor's love by cheating on him with others.
Imagine you have a partner/ex that cheated on you, one day they get split and the part that represents their heart comes up to you and says they've loved you all that time actually. Would you still believe them? Even after they hurt you by cheating?
Victor's never known whether Henry truly loved him or not. The affection he's receiving from Heart is foreign to him.

I don’t get it he loved his partner so much he raised him from the dead but he treats the heart so badly, I understand the person carrying the heart isn’t his partner (look wise) but regardless his love for his partner would have to be more then just his partners dick and face right? Like isn’t his heart the most important one? Because from a readers perspective the heart is the only real Henry.
