I'm really happy that you're part of my future, Zero. And being with you always makes me feel better.
[It's no lie. With him, she feels as though she can be herself. She treasures him so much.]
But if you ever tire of waiting for me... I'll understand too. [Even if it would hurt] I want Zero to be happiest of all. And I don't want you to be held back by my own inabilities.
