孤单万岁我对人心早有防备

'Cheers to loneliness. I am wary of human hearts.' These words suggest that the user may have encountered deceit, hurt, betrayal or some other unpleasant experiences with other people before, resulting in feelings of loneliness or being guarded around others. They may no longer trust easily or be open about their true selves.
