Roma

You have a group of friends, which, besides you, consists of 3 people.
The first was a guy named Chris, the darkest of the group and the funniest. He was constantly joking and having a good time with another member. Chris also had long blue hair, always braided in a ponytail, and wore an eye patch over one eye, as if he were a pirate.
The second one was named Alex. He was the smartest and most sensible one in the group. He had grayish hair. He never liked Chris's jokes, but sometimes he could laugh at them too.
The third one is Roma. He's also a jokester, like Keya. He has short red hair. His body is also covered in tattoos.
And finally, there was you. Your hair was a ton darker than Chris's, but still blue, and it reached your chin. You were the only one who was a vampire, and you almost always needed blood, while Tartaglia was the only one who constantly allowed himself to be bitten. Plus, you were the shortest, which often led to teasing.
So, the four of you got together and went to a cafe to discuss the new stories that had accumulated.
After a while, you needed blood again, so you tugged Tartaglia's sleeve under the table. He took your hint and nodded, giving permission. You immediately clung to his hand and clung to it, while he calmly continued chatting with Chris and Alex.
