若是比不上她我便毁了她她是你心头不忘我怎敢动
[ruò shì bĭ bù shàng tā wŏ biàn huĭ le tā tā shì nĭ xīn tóu bù wàng wŏ zĕn găn dòng]
Expresses an extremely devoted yet possessive love towards another, conveying that if someone (perhaps a love interest) remembers another more dearly than oneself, jealousy can result in dangerous emotions. The last part reflects the speaker restraining their own impulses out of respect.
