Where Rough Edges Meet Rounded Ones (слэш)

Merlin, who was in every way possible, Arthur’s complete opposite.
Where Arthur was sharp, Merlin was soft. Where Arthur was rude, Merlin was kind. Arthur’s blonde hair shone like the sun in the day, while Merlin’s raven hair reflected the moonlight like stars. Arthur’s deep plain blue eyes that met Merlin’s pale ones, with small golden flecks inside. Where Arthur was afraid to touch, Merlin was tactile. When Arthur bit back his words, Merlin rambled them.
~~~
Arthur is sharp, with rough edges and solid stone. Merlin is gentle, with round edges and a soft centre.
Merlin rounds Arthur's edges, and Arthur loves Merlin.
But his confession comes too late.
