The flashback I had in my dream still haunts me. Since Riko died after we rescued her, I can't help but put a little blame on myself for that. Perhaps, even though I returned back in time, there is no denying that perhaps I may have caused the untimely death of Riko in the past timeline. The guilt left me with some bad taste in my mouth and it seems I have yet to get over it. Maybe because the date of that upcoming event is coming, the memories that I tried to bury under all of my other memories that can't be forgotten have resurfaced again to make me remember the guilt I forcefully try to forget and felt at that time.
Despite that, I move on. The event that happened in the past timeline has yet to occur here in the new timeline and I will be making sure that it won't ever happen at all.
