(Both are each other's one and only + reunion after a long separation + beautiful, sharp-tongued older woman vs scheming, shameless younger man)
Ji Tingyu's ultimate goal is to make money, make money, make money, so her grandmother can live comfortably, just as her parents would have wanted.
Li Chuan's dream is to find Ji Tingyu and marry her, no matter what it takes.
One day, after work, Ji Tingyu went to a bar to unwind with a friend. She accidentally drank too much, and with alcohol clouding her judgment, she couldn't stop herself from following the latest trend: a night of passion.
When she woke up and saw who was sleeping beside her, she was stunned. Should she get dressed and leave right away, or just leave right away? In the end, she sheepishly slipped home.
At first, Ji Tingyu really did see Li Chuan as nothing more than a younger brother, and after their drunken mishap, she was too embarrassed to face him.
Then she realized that maybe having a younger brother wasn't so bad after all! The more she got, the more she wanted.
