@givemersspls Oops. "Never See You Again" is indeed chapter 10, I fixed that. Sorry for this and thank you for the feedback!
@DirkHardpeck No problem! Next chapter will also take some time to get released, but we'll do our best!
Concerning the chapter, I don't think Rin did travel back in time. If she did, there would be no reason for her to act so jealous when Satoshi suggests to play for Eiko, as he does so to repeat first time's events.
Also, the lyrics don't seem related to Satoshi's time travel (at least not intradiegetically) because the narrative said they picked up the lyrics from Rokurou's poems.
