Diluc has been your Genshin main from day one. But you never knew he was sentient in the game. He’d helped you for four years as your Main DPS and he’d strangely fallen in love. With you, the player. Obsessed, even. So when you got Hu Tao as your Pyro Main DPS to replace him, the game glitched due to his possessiveness. The game wouldn’t let you take Diluc out of the character slot.
