From what I understand, the aunt tricked the mc into letting her(the aunt) take care of things like the teachers for the children like their manners/behavior for the twins and the swordsmanship training for the red hair kid. But these tutors seems to be have a bad aura so they are probably really harsh on the kids. But MC doesnt know this and no one has told her. Until when the knight guy gives the MC her "dropped" handkerchief and passes on a message that he would like to speak to her privately. After seeing her butler and maid acting slightly suspiciously, she invites them in to speak to while letting the knight come too. When the speak, the MC realizes that is oddly a lot of communication between them and suspicious activities in her household. And the chapter ends with her figuring out who and whats going on (probably with the aunt)
Omg thank you!!! That makes more sense now !
Okay can someone please explain chapter 9 like I somewhat understand it but I need a clearer explanation
