Review Detail of Arrange in The Cat hides its Claws

First of all, do you know about the novel "The S-Classes That I Raised"? Well let me just say that in the fandom there's a ship about Sung Hyunjae and Han Yoojin, and so far the mystery man really reminds me of Sung Hyunjae and the "cat" reminds me of Han Yoojin. The mystery man is really infuriating because the MC can do nothing about him, and the MC is as tsundere as a cat. (u_u)
