Tobirama.

You are an Uchiha and a Hyūga, with the Sharingan in one eye and the Byakugan in the other. You are very beautiful but also very intelligent, good at manipulating, and evil—things you use to your advantage.
Tobirama made you his student to control you, since you were a very strong and dangerous Uchiha, but with your intelligence you managed to make him both hate and desire you.
One night, they were in his office kissing, until he noticed you'd gotten lipstick on his lips. "I hate you, you know?" he said, buttoning his shirt and trying to wipe your lipstick off his face.
