你为她打伞忘了我也怕淋你给他唱歌忘了我也想听
[nĭ wéi tā dă săn wàng le wŏ yĕ pà lín nĭ jĭ tā chàng gē wàng le wŏ yĕ xiăng tīng]
It means you provide shelter (physical or symbolic) for her without thinking that I may also need such care; you sing songs to him forgetting I want to hear you too. This nickname expresses feeling overlooked in favor of others in matters of love or affection, revealing a heart full of yearning yet unnoticed feelings.
