你未熟识于我我未深交于你
[nĭ wèi shú shī yú wŏ wŏ wèi shēn jiāo yú nĭ]
It conveys an acquaintance not fully developed between two people - 'I am not deeply familiar to you, nor are you truly intimate to me'. Expresses an initial stage of relationship building where both individuals still maintain distance and don’t know each other too deeply.
