The story of a math master in his previous life who was reborn as an ordinary high school sophomore and got a boyfriend who was a top student in his previous life is actually a fanfic of Guo Wentao, Pu Yixing and Tang Jiuzhou. It is an absolute sweet cookie, please feel free to eat it.
The author is a newbie, and his writing style is that of a primary school student. Please give me some light feedback.
