I think its not a matter of the vampire not loving soohin it was that he was able to come in easily take soohin away. he didnt realize the extent of the abuse soohin went through. He only saw what was on the surface and now he knows what is underneath it makes him sad for maybe not being there sooner, But ya sungha needs the most painful death possible how can you abuse this kid to this extent and still walk around like you are a good person, he sees nothing wrong with the way he treated soohin. sad sad sad
