Diluc, he went missing two years ago. No one has seen him and everyone was so worried at first.

Kaeya has been frantically looking for him for these past two years

He had no luck though, unlike You

You we’re walking through the woods of sumeru when you found a man,he looked like diluc except his hair was much longer and he had a lot of injuries.Diluc noticed you and he realized who you were,he ran towards you, tears in his eyes and he was yelling out the words “MOMMY!”
