My favorite character is Sayori. I like her a lot because I can relate to her, taking great care of others instead of myself (and also the hiding depressions stuff). When it was the day before the festival, I was so happy when Sayori came over just as Yuri was about to leave. The conversation between the MC and Sayori was very painful to read until I was given the choice, "Sayori, I love you," I picked. That changed everything for me. I thought things were going to get better from then onward... until the next day came around. Sayori was late to school, but strangely not there. Going back to her house I could really only think about what could have possibly happened. "I gently open the door"
I want to hang myself after that.
It was tough going through that. I actually started crying. The bond between the MC and Sayori is a lot like me and my best friend. She was the MC, and I was like another Sayori. So obviously, this scene struck me where it hurt.
