Why does curvature reduce the inward attractive force of molecules

I am struggling to visualize why molecules on the flat surface experience more net inward force than those on a curved surface. If we have 2 surfaces of water which both have the same number of molecules and one is curved, why does the curved one experience less inward force, if anything, to my mind it seems as it would experience more force as it is more compact. Additionally, does bigger curvature imply less surface tension and why?

From what I understand, this force comes from the hydrogen bounds between molecules on the surface. On a flat surface they are packed closer to each other, so there are more hydrogen bonds. on a curved surface they’re further from each other so there are less hydrogen bonds
