人潮拥挤我需要你y人心可怕我保护你y
[rén cháo yōng jĭ wŏ xū yào nĭ y rén xīn kĕ pà wŏ băo hù nĭ y]
This is actually two sentences intertwined: 1) 'In a crowded place, I need you'. This part describes a situation where one feels a deep longing for another's presence amidst a bustling environment. 2)'The fear in your heart, I will protect you.' which means they offer protection from fears or dangers that threaten the safety and happiness of their loved one.
