苏雨沫陈靖依99
[sū yŭ mò chén jìng yī 99]
Seems like it is made up from names 'Su Yumo' and 'Chen Jingyi' with '99', possibly a couple or very close friend pairing these names together along with a special number '99' which could mean anything depending on context; maybe a significant year or day, just an attractive combination of digits or internet slang (9 representing long-lasting as in Chinese pronunciation).
