做你的妃守护你做你的王保护你
[zuò nĭ de fēi shŏu hù nĭ zuò nĭ de wáng băo hù nĭ]
'Be your concubine to guard you, be your king to protect you' implies a fantasy-like role-reversal where both partners are ready to switch their identities - from the submissive caretaker to a powerful guardian - depending on circumstances, highlighting the balance between intimacy and strength within a partnership.
