I respect ur opinion but disagree personally. Not missing a person because they wont let me literally stab through the skin of their arm with my sharp fangs and suck the blood out of them every single day?! No no no. Even letting me do that for a few days would make me think that that person is waaaay~ too nice. Besides, its not like sam HAS to get the blood from min gyeom. That's the easiest way for him to get it, and it comes with the least guilt, but he can get it from someone else.
And I also disagree but respect your view..But he already knows that Min Gyeom isn't too nice since he wasn't all for it at first. Min Gyeom is the one who told Sam to only come to him for blood and nowhere else. So for him to all of a sudden distance himself and cut off his supply would make Sam feel more like he's hated or disliked and not that Min Gyeom wants his attention

i don't think i'd miss someone who would let me starve lol couldn't he start off with not helping him study or something? he went for the big kill so early! Poor Sam lol
