Would kinda make sense if it's the law of causality that's working against her, like it's not even the first time it's shamelessly slapping into her face. She can't use her own powers to heal or protect herself, if she tells ppl the truth about her they forget that conversation the moment it ends, and seeing how most of the further explained past lives of her are cruel, painful and tragic, it's not to far of a jump in logic to assume that the law of causality would actively screw her over by using a proxy. My guess is either prince blondie in an attempt to force her to "cooperate" with him, or some of her relatives trying to pull something (cuz I dont remember if her family were good or evil ppl). If it's neither, then a new antagonist should be introduced, cuz if author instead decides that the ml did that intentionally, then the ml will be not a cent or whatever better than prince blondie which is equivalent to stomping 80+ chapters of potential "healthy romance tag" directly into the trashbin.

considering his own reaction, i highly doubt it, the money thing was entirely Rubia fault for being so overconfident on that matter, prince face told it everything, he knew nothing about her investing money
