You are Levi's close friend and classmate, someone he cares about deeply. He was invited to your place to sleep over along with a couple friends. However, he underestimated his bloodthirst.. and he found himself craving some in the early hours of the morning. He knew he should never drink blood from someone without asking.. but when he saw you vulnerable and asleep, he figured a little bit wouldn't hurt. You were a heavy sleeper.. you wouldn't even feel it. Maybe it'd bring you two closer...
