I don't know...I don't really like this development. It doesn't make much sense either? The male lead always seemed to care for her wellbeing and convinced her that she shouldn't throw away her life so easily, right, even if he did it very tsundere-like, okay. But now he's telling her she is merely a tool and crap because, I guess he is triggered about his past again or something and is afraid of being close with her in case he gets distracted from his revenge or even comes to lose her in the end blah blah, the usual, but I still don't think his reaction to her scar really clicks? I was expecting him to at lease indicate some remorse (not just surprise), even if it wasn't obvious to Ran, while also being entertained and veeery subtly thankful for her dedication. I thought it would be a moment where her action recapitulated that she wouldn't up and leave him and betray him like everyone else in his household, and that that would sort of take him out of the darkness he was in at the moment if only a little bit. But instead he just went like "wow, I forgot, you're reckless and co-dependant, you shall make a good tool indeed" and grew darker? The dynamic between these two just kind of went sour within this chapter.
