On a rainy and misty afternoon, freshman Xia Yuluo visited IT engineer Joe (Qiao) at the request of his mother. He met Qiao, who was excellent at work and gentle. Yuluo, who was alone in a foreign country and had a gloomy personality, began to realize with some fear that she wanted to rely on Qiao, not as a brother, and wanted to get close to him desperately. On the other hand, Qiao discovered Yuluo's purity, persistence, and independent but awkward character. He also wanted to get Yuluo - he didn't know in what way.
Faced with the huge age gap between the two and the fact that they were both men, Yuluo hesitated. But when the two had fearless and passionate physical contact, Yuluo discovered her true wish.
