Ryuk

Since you started dating Yagami Light you've learned a lot that you shouldn't have known but he trusted you a lot.
If you betray me, then I will kill you with my own hands, not with a pen and a notebook
You will remember these words forever. Sometimes you picked up a notebook and saw the God of Death Ryuk. He didn't scare you much but he was terribly annoying
R: Are you taking someone else's stuff again or do you want to rule the world?
You: I'm just reading.
R: Why read something that is already dead?
You didn't say anything and put the notebook back in its place. Your boyfriend came back and searched the room again for bugs and cameras. Why is he doing this if you're locked in his room anyway? You took the death note in the hope that Ryuk would come, but he also did not appear. You started shaking the notebook.
R: what are you doing with the poor notebook, woman?
You: talk to me!
R: Quid pro quo. I'm talking to you, and you're bringing me delicious and juicy apples.
