"You know I wanna see you even if I ain't investigating anything?"

Pushing the point.

Louis can't say the important things. Can't say what matters, no mater how deeply he feels it. And Daniel must know this, or at last, have the shape of Louis' failings when it comes to those he cares for the most.

But he can say this. He always wants to see Daniel. His door will always be open for Daniel. And for now, that can be enough.
