情癌病者孤独患者
[qíng ái bìng zhĕ gū dú huàn zhĕ]
'Romantic Cancer Patient/Solitude Sufferer' is used sarcastically here by netizens who consider unreturned love as a chronic disease named 'romantic cancer'. Simultaneously suffering from loneliness, this internet name reflects their pain and melancholy due to an obsessive but fruitless romantic relationship.
