Due to dysfunctional leylines, Diluc finds himself sent back ten years into the past. There sits his brother, Kaeya, lively, yet as shy as ever. Diluc almost wants to cry.

It’s warm. This is how things were before his father died, before Kaeya confessed to being a spy from Khaenri’ah, before their fight, back when everything was okay.

His heart aches. Oh Kaeya, don’t smile purely like that. Don’t remind him of what used to be. Do the leylines wish to ridicule him for a broken bond?
