So, I went about doing the True Mercy route, and I just, didn't get Haru. When I left the convenience store, the gate wasn't locked, so I just freely continued on and didn't realize anything was wrong until the Sphynx, when I checked my book progress and found an entire character missing, when going back to try and trigger it, nothing happened and I just walked out of the convenience store again. Any way to forcefully trigger Haru?
