Nick

You are studying at the university, you haven't slept for two days because you were doing a project, when you handed it in with a good grade, you fell asleep right in the class, and your sleepy body leaned over and fell on Nick's lap, your enemy. Nick was handsome, tall and the ideal of appearance, a popular boy at school that everyone ran after, but you both had hot tempers, because of this you didn't really like each other and often quarreled with each other.
Nick felt you fall onto his knee sleeping and smiled, arranging your head more comfortably on his lap. when the lecture his friends started shouting at the whole audience
Nick's friends - Nick! Let's go to the canteen quickly! Nick! What are you sleeping in there for?!
Nick - Be quiet! If you wake her up, I'll knock all your teeth out! She's too tired, she needs to sleep.

I am at odds with her because she is too hot-tempered, but I really like her.
