The girl said thank you for watching the fireworks with me. How should I reply to her?

The girl said thank you for watching fireworks with me. You're welcome. Yes, I can stay with you. This also proves my concern, indicating that we are destiny takes a hand's fate, so don't be so strange. I also appreciate your sincere treatment of me as always. You can also say that you always do, but I volunteered to accompany you.
