If there was any doubt in my mind how Chako felt about Reiji, those doubts have now been completely cleared. She didn't even see Esemori as a person, but rather, as a novel; a clear indication of her obsession with being a heroine. Essentially, Esemori didn't really mean s*** to her. I thought her calling Reiji as "Esemori's lover's son" or whatever instead of just "Reiji" some chapters ago meant she no longer saw Reiji as a person, but as a plot device. But no, she was just misguided by her obsession; seems at the end after overcoming it, she dropped that obsession for Reiji. Probably about the best conclusion I could ask for in this situation.
Reiji however, I'm still not sure. Instead of getting Chako help, he was more insistent on taking her to Tokyo for some reason. He was also simply going to walk away after Saki said she'd call an ambulance. I'm not sure if that's good or bad, as either he might have thought he was in trouble with the officers and wanted to escape, or, he was looking for death once again, and once deterred, decided to move on(whatever that may mean). At the end there, he didn't look enthralled about "getting better". Curious to see what kind of turn he'll take at this juncture.
Can't believe this manga gaslit us again. Made it seem like Chako had done something irreprehensible, cause she had a knife in her hand(and didn't use it to attempt to kill herself). That, coupled with her proclamation in that moment, meant the most obvious conclusion would be she stabbed her father, or mother, or both.
