公主不能没有小怪兽
[gōng zhŭ bù néng méi yŏu xiăo guài shòu]
A princess cannot be without her monster, hinting the relationship or companionship of two opposite personalities or aspects. It's somewhat playful, suggesting a girl's fantasy with a 'monster'. It’s a fun take on how different entities fit together, maybe showing opposites attracting or complementary traits.
