别爱我会心碎
[bié ài wŏ huì xīn suì]
Translates to 'don't love me, it will break your heart'. Used either ironically to deter potential admirers/lovers because one sees themselves as unlovable/damaging, warning of future heartache for others if they were to fall for this person - essentially conveying feelings similar to 'stay away from me for your sake.'
