"What does this mean ?"

The first drawing symbolizes the comfort and the innocence in which we grow and build what we are.

The second drawing symbolizes the roughness when we encounter another (very close) one, and when we have to lose some parts of what we were to fit together.
We also undergo cracks, or maybe tears, in our persons.

But, just at the surface of that encounter (at its perfection, at the most successful matching), there, there's the possibility of a kind of a perfect glide. Maybe as soft as the softness in which we had grown.

Based on that new fruitful softness, we can then build a third person : "us". Or whatever will happen from that "us".
