Fujoshi-san's manga / #4p(2)

I added four stars coz the side story is awesome aside from turning omega after waking up to the past and aside from being pretty and aside from 3 handsome guys the story was 1/5 satisfaction ofcourse it was too fast but how did he turn to omega when in his first life he did not manifest, but seriously I wanted to know the former husband what he truly did... ghod
