In their previous lives, Gu Nanzhi and Zhou Shi'an were an ill-matched couple who had muddled along together since childhood before getting married. Their ten-year marriage was spent entirely in arguments and cold wars.
After dying in a car crash, they were both reborn at eighteen, on the day they had to submit their college entrance exam preferences. They swore to themselves at the same time: In this life, they were absolutely going to stay as far away from each other as possible!
Zhou Shi'an: She hates the cold most. I'll apply to schools in the far north. There's no way she'll get in!
Gu Nanzhi: He hates the cold most. I'll apply to Harbin. There's no way he'll be able to stand it!
Then two acceptance letters bearing the name “Harbin Polar University” landed on the table at the same time, and they both completely broke down.
