She's coveting her own half sibling.

No, the current duchess is not the biological mother of both ML and that blond. They're the children of the late duchess, ML is the legitimate child of the previous sovereign lords while the blond is the illegitimate one as the late duchess was forced and raped by the previous emperor. They're related by maternal blood so they're half siblings.

Also, she got some disappearance from the story and comeback as the illegitimate child. She's sly and the current duchess is in favor for her due to being commoner and that two face skills she have sth like that but thanks to ML the truth uncovered and she was scorned by wearing the FML wedding dress and destroying it lmao.
He clearly doesn't understand the situation. All words came from his mouth is pure hypocrisy! So, all the things that students exert their high status to the people with low one in the academy will be end by a mere apology!? Talking about the academy rules, your student is being bullied by everyone and this mf instructor just thought about respecting the rules? So, if one student die from that? Then will that instructor "respect" to the rules be reasonable excuse!? No.
