腐入人心
[fŭ rù rén xīn]
Literally, 'Decay Enters the Heart.' This name likely conveys a deep and melancholic emotion where negative feelings like disappointment or sadness have deeply impacted one's heart. It might be expressing someone who is in love with something not socially accepted (like same-sex couples' love in some context, noted as BL culture), indicating that unconventional love touches them profoundly.
