After Edden found out that Gojo killed her parents they bond broke,she hated him,(and in the same time loved him,but she didnt wanted to admit herself) she atempted to leave of course but Gojo didnt let her,so they made a deal,because he was the one burning her house he owns her a place to live,there was no love no feeling to keep them together,only that deal-she trained....later ,after 4 years,when he became a teacher he was teaching his students too,even that she was trained by him....there was no exchange of words between them two,and even if it was,it would end up with an argument
