(My character) is just chilling, having fun in there life when a person hops through the window. (Your character) is a serial killer on the loose. Our characters are friend, and as you hop through (My characters) window covered in blood, (My character) realizes that yours is the murderer. They decide its fine, wore worried about why it doesn't bother them. They have had a crush on (Your character) for the longest time. (Your character) knew this, that's why they came to mine.
(Your character) explains that they like mine too, and basically kidnap them,. The twist is, my character has secretly always dreamed of this, having a bad backstory (Depending on what your comfortable with) and has always wanted to be taken and hidden away from the world.
This should be a fluffy relationship, with fucking only if wanted. the top/dom would be possessive and very clingy.
