Mu Yunshu returned to teach at the school where his younger brother was studying, only to find that his roommate was the senior he had been secretly in love with for several years.
It was a God-given opportunity. Recalling the past holidays between himself and his senior, Mu Yunshu decided to socialize well and at least become his best friend.
So Mu Yunshu decided to work hard, study Mathematical Olympiad hard, and strive to have a common topic with his seniors.
"The Mathematical Olympiad is still too difficult. I'll just be a rotten, smelly salted fish."
"Difficult? I can teach you."
Intention: Blow away all the sand before reaching gold
