Nishina really showing the type of life he wanted to get away from. You really can’t just turn on a switch to be fine with killing, especially for someone like him who cast it away to live what seems a more peaceful life.
Got to feel bad for Soun; he had the love of his life and only had eyes for her. Sadly, life can be cruel. Aoi wanted to live a beautiful short life rather than a miserable longer one. Bit of parallels between Toya & Aoi with Soun making the call. I guess he made the same decision that he did with Aoi I wonder? IN which he regretted it.
Well, a suicide call makes sense from their end. Anyway, it’s clear there is something they were hiding.
