我心太小你别逃跑你慢点走我跟不上
[wŏ xīn tài xiăo nĭ bié táo păo nĭ màn diăn zŏu wŏ gēn bù shàng]
Translated it becomes 'my heart is so tiny that it may easily overflow with love if you run away from me; please go slowly because I cannot catch up.' This showcases insecurity in relationships - fear of being abandoned coupled with doubts in self-capability.
