You're More Bewitching Than Wine

Love kept unspoken is a secret crush. When Jian Ning was young, her love for Bai Yuanzhou was a grand, public declaration. Even years later, Bai Yuanzhou still remembers the brazen little girl who confessed to him, and he accepted this job for her sake. But before he could confess, her drunk self blocked him with the person beside her... Did she have a fiance now? Bai Yuanzhou's face instantly turned bright yellow, just like a lemon. "Everyone in the circle knows the new consultant loves lemons!"

Note: Mutual pining. The wedding news and the supposed fiance are both misunderstandings. She is truly single.
