Lu Yuan, a 28-year-old social programmer, died suddenly due to continuous overtime work. He opened his eyes and returned to the senior high school classroom in 2010. Relying on his mind from his previous life, his experience 10 years later, and his (half-baked) future memories, he decided to stay calm and avoid being included in the college entrance examination, invest in buying a house in advance, and stay away from PUA in the workplace. But he didn't expect that Su Nian, the Bingshan top student who ignored him in his previous life, would actually take the initiative to be his deskmate in this life?
