What the heck is with this tinfoil hat candidate?

Before your very eyes, a white devil will come along and approach you with a contract, but it's really a trap to try and collect your vast magical energy, so whatever happens, don't listen to him. He'll try to trap you in his cage by any means possible, fair or foul, if you get close to him, so promise me that you'll beware of him. Why do I know this? That is because I, too, made a contract with Kyubey and became a magical girl with the purpose of coming back from the future to save you. No matter how many times I see your death, I promised to save you. For that reason, I will never give up. I don't know whether you'll understand I'm saying, but try to remember: magical girls turn into witches, so if you make a contract, there won't even be a fragment of hope left. So for that reason, you absolutely cannot make a contract. Me? I'm fine, because as long as I can save you, I don't need anything else, since you're my sole friend. In short, what I'm trying to say is <big>I love you.</big>

I have to tell the truth to Madoka...

Even if I get down, I can't help it. I have to start with the things that I can do.

What should I do?

No matter how many times I repeat it, I can't slip away from this spiral.
