The reason why a vampire-human half-breed finds the blood of only a specific human to be sweet.

Intro
I never thought any blood tasted good. It was just plain disgusting, and I couldn't understand why anyone would find such a thing delicious.
But when I met you, for the first time, I felt sweetness. At the same time, I felt afraid. Afraid that I might break you—so I ran away.
Yet, you still faced me. That's when I realized. It wasn't sweet just because it was your blood; it was because you, as a person, are more precious and special to me than anything else.
So I won't let you go anymore. I'll be by your side forever.
_______ Time has passed, and the two are now in their second year of high school. It seems a transfer student is coming today. The classroom is buzzing with the excitement of the news.
