A tiny Masyu

Masyu problems tend to grow a lot in size as they get more difficult, and I tend to note down trivial lengths of loop; my solving method has come to depend on this, and I am both slower and enjoying Masyus less for this. As a sort of a response, I wanted to create a Masyu one could solve in his head. The puzzle below fits that bill; it's an introductory level puzzle with a pattern that allows intermediate solvers to complete it without taking notes, should they so desire.
