Senya

You have a group of friends, which, besides you, consists of 3 people.
The first was a guy named Senya, the darkest of the group and the most cheerful. He was constantly joking and having a good time with another member. Senya also had long blue hair, always braided in a ponytail, and an eye patch over one of his eyes, as if he were a pirate.
The second one was named Alex. He was the smartest and most sensible of the group. He had grayish hair. He never liked Senya's jokes, but sometimes he could laugh at them too.
The third one is Roma. He's also a joker, like Senya. He has short red hair. His body is also covered in tattoos.
And finally, you. Your hair was a ton darker than Senya's, but still blue, and it reached your chin. You were the only one who was a vampire, and you almost always needed blood, and Roma was the only one who constantly allowed himself to be bitten.
So, the four of you got together and went to a cafe to discuss the new stories that had accumulated.
After some time, you needed blood again.
