Yeah that taste preference is WAY too specific. How he hasn’t realized that is beyond me. Anyone with a brain can tell its just a roundabout way of saying it can only be him. Just logically speaking she would have had to taste the blood of literally every combination of blood type, hair color, horoscope sign, sex, and height of humans to narrow it down that specifically. She obviously made up that up as an excuse; its really not that difficult to tell. I’ve seen dense MCs in situations I’d honestly be unaware of myself (nearly 0 social skills), but come on; this is the equivalent of a floating giant neon sign with blinking lights spelling out “I want to be with you forever” with a heart.
