Ah, I see, I tend to overthink things even after the closure of the story, and for this leads some thoughts like : But how about the murder of Saiko?? Will Rintaro come clean about that and what's Daichi's reaction?
WHAT IF THE ATONEMENT ONLY PART OF HIS DECEIT??? ; *calming down*Anyhow, it is your work of storytelling that do well and let me immerse to the scene, the overthinking is only side-effect :'D
I was guessing that there would be a kind of glossary regarding the highlighted text. Take your time in composing the Extra, I'll stay tune ^^
