Xiao gets into a big fight some other god or something and he is on the verge of death when Aether finds him on the ground bruised and bleeding knocked out.

*goes to a mini cut scene of Xiao fighting and getting hit by a giant rock but still fighting.

Aether and Xiao like each other but Aether was too awkward to ask the Xiao out, Xiao didn't want to get his hopes up and didn't know how to ask Aether out but they were both flirty with each other and protecting each other all the time. Everyone knew they like each other but they both were oblivious as hell.

Aether runs to Xiaos side and holds him with tears running down his cheeks thinking he's dead. Xiao opens his eyes and looks Aether in the eyes and smiles. "Took you long enough." With one eye half open. He carresses Aethers cheek and looks into his eyes and before they knew it they kissed. Xiao pulls away "Live for me" he says before he slowly goes limp and his life slowly drains out. Aether puts Xiao down slowly and gives him one last kiss on the cheek. He turns towards the enemy and pulls out his sword and glares at the enemy.

*this is where the part of " even if heaven won't take me back"* Aether starts sprinting toward the enemy while dodging all the floating rocks being thrown at him and uses his anemo abilities and glides in the air and goes above the enemy and falls down stabbing the enemy in the back. Aether jumps back and breathes out of breath. All of a sudden a flash happens blinding Aether and goes behind him and with a charged punch, punches him in the back and into the air. Aether coughs up blood and falls to the ground near Xiao. Xiao was getting paler by the second and by then Aether was furious. Aether on his hands and knees looks up to the enemy, who is smirking and hovering above him.

Aether grits his teeth and turns grim before a burst of energy comes from aether and anemo wings form. Before the end of the song it shows aether with his sword using his wings and going 1v1 against the enemy like face to face
