Gu Lao (played by Eric Tsang) runs a noodle shop with his son Gu Feng (played by Zhou Junwei) and daughter Xiao Gu Gu (played by Lai Yuen Tung).

Gu Feng is dating the cute and kind girl Carlily (played by Rainie Yang), marking his sweet first love. However, Carlily's sister Heman (played by Guo Shanyu) doesn't think highly of him. The two unexpectedly work together seamlessly in a competition and win a free vacation to Japan. Of course, Heman gracefully allows Gu Feng and her sister to go to Japan together. However, during their vacation, the previously antagonistic Heman and Gu Feng spark a clever connection through phone conversations. Watching his happy and innocent first love, Carlily, how will Gu Feng face his first major choice in romance? Meanwhile, Xiao Gu Gu and the orphan Wei Long (played by Zheng Daoshan) are also experiencing a budding love, and the air of this summer is filled with romance...
