做不了你女人就做你后妈
[zuò bù le nĭ nǚ rén jiù zuò nĭ hòu mā]
'If I Can’t Be Your Woman, I Will Be Your Step-mother' suggests a possessive relationship. It indicates that although this person can’t enter into intimate contact with you (being a lover), they still insist on participating in some other form within your life (stepparent role), revealing strong possessiveness over loved ones.
