You're already in my future is from the movie Send you a little red flower.
The exact line reads:
Ma Xiaoyuan: I was afraid you wouldn't take me with you if I told you. I want so much to be the one standing by the lake with you, but unfortunately I'm not, and I'm not in your future.
Wei Yihang: you're already in my future, we crossed the white shark beach together, we floated on the Dead Sea together, we also went to Antarctica to see the penguins, we went to school together, graduated, got married, had a child, and we are old enough to still square dance in the square! I've seen all of these and I just didn't tell you.
Ma Xiaoyuan: You're lying, that's a silly thing we did together, not the future.
Wei Yihang: adults only think about silly or not, children only think about whether it can become real, you wait! In the future I'm going to take you all over the world.
Ma Xiaoyuan: What if we get separated?
Wei Yihang: If you get separated, you can raise your arm in the crowd, and as soon as I see this little red flower, I'll run right over to you.
Ma Xiaoyuan: the painting is really ugly, take me out for a walk!
