Let's Do It Again, Smash the Dragon King's Mouth at the Beginning

Mulder, the chosen one in the eyes of others, is the eldest son of the prestigious Mu family group in the city. But in fact, he is a supporting character who is slapped in the face at the beginning of a routine novel. In his previous life, Mulder watched helplessly as the protagonist with whom he had a long-standing grudge married and exploited his sister Muse. After the marriage, he had many affairs, and even allowed his confidante to humiliate and bully his autistic younger brother. Once again, he decided to interrupt the spell first and tore the protagonist's mouth out first. At the same time, something seemed to be changing. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
