In the corner of Taipei, there is a quiet and elegant coffee shop. Its owners Duo Er (Kwai Lun Mei) and Qiang Er (Lin Chenxi) are beautiful sisters. Duoer's idea of running a coffee shop has a long history. By chance, she was able to realize her dream. Despite a lot of efforts, the coffee shop gradually fell into silence after the noise at the beginning of its opening. Just as the two sisters were worried about this, a Thai cookbook sent by a friend to celebrate the opening of the business inspired the "geek" Qiang Er.
