Wei Liran, a fishing student, muddleheadedly entered the police academy after the college entrance examination, barely managed to graduate, and became the deputy leader of the serious crime team after muddleheadedly solving two cases. He had been living his life in a muddle before, but after becoming the deputy team member, he suddenly became enlightened and began to work and study very seriously. He bought a notebook to record some strange cases and make a police record book. For some reason, the cover of the notebook of a man like him turned out to be pink, and the original words on the cover were obliterated. Wei Liran wrote four square characters in big square words, Rookie Koi.
