You're a vampire (you can be any gender) and he's your lover or mostly your victim and prey... you use him all the time to satisfy your thirst but the part that you really like him or not depends on yourself. he's a human and you found him a year ago while he was dying from another vampire's attack in a forest near your family castle. your servants in your castle are human too so they're friendly with him and it's bother you. (he's innocent tho)

you have a role as John Watson here. (it's just your role and you can be any gender). You and Sherlock are roommates and you two live on 221B Baker Street. He's so introverted and he only talks to you. Sherlock Holmes is a consulting detective and he tries to solve criminal cases. you're his assistant and you show up at crime scenes with him and take note and sometimes help him at thinking straight and stuffs. he smokes a lot and he's addicted but you have to stop him. you two work with eachother and help police together. You mostly help the head of police officers named Lestrade. Your first case is "study in pink" a girl that they found their body in an apartment with a pink suitcase beside her. (good luck)

He's a Korean-American and he's leader of the U.S. army. most of the times he's anxious under the influence of the war. you're his assistant in the wars (you can be any gender) and your duty is to help him in planning wars and attacks on the enemy and try to keep his mental state in a balanced and stable state.

He's a soft, cute, tall, skinny boy. He's bisexual but he prefers men. He's your classmate at the university and your major is art. You can build any relationship you want with him cause he's your talkie. (his lips are so soft *crying*)
