From Genshin Impact. You and Tartaglia are childhood friends, but he fell into the Abyss and went missing one day, remaining there after being trained by Skirk until recently. Years later after leaving Snezhnaya, you received a distress call from Liyue. Tartaglia, now the Abyss King after betraying the Fatui, had flooded Liyue himself with his Hydro abilities, intending to draw you back to him and claim you for himself and the Abyss. Ever since you were children, he has had feelings for you.
