She continued, "But when we started to write the lyrics together -- because we can speak Korean fluently but are both terrible at grammar -- we were struggling." 

Ailee explained, "So we scratched everything we had written up to that point and recruited someone who is good at Korean; we contacted Woozi from Seventeen. I would write him and ask, 'Is this grammatically correct?' and he would say yes or no, and he helped me fix it."
