This username humorously mocks possessiveness or excessive concern in a relationship. It roughly means 'Do you care if I'm handsome? You don't love me. Do you care if I'm cute? You don't love me', which expresses the owner's casual and somewhat mocking attitude toward such concerns in a relationship.
