Rape?

I dont know if this anwers your question but in their past life, Kwon Ido's brother Kwon Ijung raped sejin saying that Ido give him(sejin) as a gift. If i remember correctly, Ido got mad and shit that sejin was fked by his own brother

????? After Ido’s brother raped Sejin, Ido raped him too. Him getting pregnant and not knowing which child it is made him kill himself (along everything he went through)
