In the first fifteen years of his life, Xia Yang was a product of the "three noes" with no friends, no money, and no education; until the summer of his sixteenth year, he received a letter and a bank card.
Under the temptation of the sinful bank card, he enrolled in an ultimate high school for boys according to the requirements in the letter.
As a result, Xia Yang met a group of people in this boys' high school - including the weird rich second generation, an atypical illegitimate son, a mysterious academic master, the product of a single-parent family, a suspected alter ego, and a former friend who proved that time is a butcher's knife - after which he finally understood his destiny:
"My brother told me to go home and do my homework!"
Don't ask where he came from, just ask about a murder caused by a bank card and a letter.
Purpose: Learning is the greatest step towards human progress.
