Never read Ennead so not sure what type of rape it is but yes... So far MC got raped twice by 2 different MLs. Though one of the other ML, RESPECT MC and chose not to when he had the chance because he knew it would harm MC more that anything else.

1st time was more dubious consent with the general while drugged by another. He didn't really mind that much it seems and did admit enjoying it afterward (discover his Og body was gay so physically not a virgin though psychology he was). If I don't remember wrong.
2nd time was full on rape by the @#€&€# Prince of Yu (Emperor brother) who got crazy after being reject for the xth time and seeing love mark on MC. Even continued after MC passed out twice. Wtf?!?
please tell me it's not ennead level rape
