Excellent TL Note, definitely would've missed the nuance on that ch title as it was in English. Think you still pulled it off well enough as the consternation is palpable in the build up during this chapter to carry through that underlying frustration with, "What am I even doing right now?" Without being said, that question is playing out repeatedly in the background of not just the chapter, but the whole manga and like a rubber band under tension it snapped, both in the past and the present, that became the driving force of Mio to act.
Thanks for the ch, and these TL notes have always been great insight into the deliberation that the author writes with!
