As you can see on the images below, my problem is when I crease an edge to get sharpness with "Subdivision surface" modifier on, eventually, I get that pointed convex edge.
How can I avoid this 'bug' without complicating the topology, because obviously "mean crease" doesn't work, as well as making vertex group of the vertices on this edge and using it with the "Bevel" modifier.
