爱过的人叫瘟疫

'The One I Loved Is Pestilence.' An emotionally charged moniker conveying complex and somewhat negative sentiments. Here 'plague' doesn't refer only literally to disease; metaphorically interpreted, it can signify that love sometimes brings pain, suffering, destruction or disaster-like impact (in terms of psychological state) onto one’s mental health due course post relationship. So, such naming conventions tend to depict heartbreakers who cause hurtful aftermaths.
