In front of the teaching building, fourteen-year-old Xu Can was sitting in front of the steps crying uncontrollably, when a voice suddenly came from overhead and asked, “What’s the matter with you?”
She was so frightened that she raised her eyes, and was amazed again.
With tears in his eyes, he sniffed and held it for a few seconds, not wanting to tell the truth, “Teacher, I… I didn’t do well in the exam.”
Tong Mingyue sat next to her and chatted with her.
The next day, Tong Mingyue passed by the school’s display board.
I saw that Xu Can, who spent a long time in teaching her classmates who didn’t do well in the exam, ranked first in the overall ranking list, and almost got a perfect score in every subject.

When I opened my eyes again, the computer was lit up with a blank document.
Back to sophomore year.
Failed subjects, no money, there are still two professional exams in sight…
In this life, Xu Can walks without heart and heart, with eyes full of eyes, only Tong Mingyue.
