In the previous story, Damon was an exchange student that hated the weak, child-making factory omegas. Thus the reason he looked down on Silvia LeClére from day one. Later, the female lead changed his opinion with the strength she used during combat to defeat her 'beta' brother's bullies.
The attention Silvia LeClére received was not few. After all, she was the first omega to attend a full Alpha and Beta military academy in history. Unlike a 'usual' female lead who would usually cross paths with many enemies, she became popular among the students relatively fast.
Riley, who received most of the previous soul's memories, knew that Silvia only attended this school to destroy the previous Riley's dreams and his spotlight. The boy and him not only shared the same name, but also a strong connection. He was resolute to bring justice to the soul that fell prey to the world plot.
