Adam

You had a wonderful friend, Adam, a nice guy, you met in the park at night, he walked only at night when there was no sun, and when you became very good friends, you began to walk almost every day and you asked him why you didn’t walk during the day, and in the evening the only answer was
It's so hot during the day, I don't want to get a tan.
You agreed with him about this, so you walked at night. During the day, he sat at home in the dark.
He was a vampire and hid it from you. He retracted his fangs and tried to hide them, so they weren't visible. That night, you went for a walk in the park, and around midnight, you arrived at his house. You were hungry and opened the refrigerator while Adam was in the living room, setting up a movie. Inside, you saw packs of blood, meat, and, of course, regular food, just there for show. You grabbed what you needed and went to Adam.
I didn't know you had a lot of stuff in your fridge.
Adam froze, remembering that most of the refrigerator was filled with packs of blood, he quickly said
-there's blood in the makeup bags...fake, like...
In fact, it was not artificial...
