Vandalizing (NANABAKA X Reader)

(Y/n) is a talented gymnast. She can do any flips you ask of her and can even do flips on beams and bars. She is one of the best. But there is a side no one knows of her. She sneaks into train stations to vandalize trains by spray painting on them. That's the one thing she actually enjoys doing. She has two worlds. Her world, and the outside world. She does her own thing in her world, but on the outside world, she does what people expect her to do... Until she met 4 men.
