One day, Valentine, a female college student, went skiing sleepless nights in order to get a teacher qualification certificate. Unexpectedly, she met the musician Edward there. They fell in love at first sight, but fortunately their relationship was limited to the relationship between men and women before the exam and did not touch their feelings. However, she didn't realize that the natural charm of a man with only one-night stand value is beyond her control. Ned is anxious, fanatical and impulsive. He was born for music and played in nightclubs for a living. They seldom meet each other, and only complain to each other by phone late at night. A lightning-fast tryst, every minute counts, and how much tenderness and tears have been produced. Unexpectedly, the phone call caused a big storm, and Valentine wanted to break up with him. However, although Edward used to be bohemian, he couldn't help running to Valentine's examination room. When she saw his haggard appearance, she found that she really loved him, so they embraced in the sun.
