Summary
Just like with any other breakups, there are things you need to sort out — each other's belongings in the home that you once shared, a joint savings account to be closed, and many more.

Summary
Aether knew he was fading. The stars were telling him to go back home. He took a deep breath, letting the breeze caress his face and kiss him like an old lover. He looked at the skies and wondered if he truly belonged there when all the people he loves are at an arm’s length now. Is it greed? Aether wondered.
Maybe not. Maybe he's also just starting to finally find his place too..
A place just for him.
So, before he fades with the stars, he wanted to spend his final Lantern Rite with Xiao—the man he loved for all his time in Teyvat-- only for the Adeptus to ditch him at the last minute because of his fear towards his karmic debt.
A story of love and second chances. Will Aether disappear, or can Xiao save the enigma that landed in Teyvat and realize that Aether is...
a star just for him. -

Summary
It seems that the traveler is really like the sun. He makes the world feel like a slightly brighter place. Lyney then thought that maybe one day, Aether will be written in history books, will be written by bards, a living legend to be admired by sailors as they drink booze at night.
Lyney is a lot of things; a great magician, a Fatui, a vision holder. The only thing he is not is an emotionally intelligent person. He had no idea why he felt this way about Aether..but right now..he wants to know more about him..
And he wanted the traveler to know more about him too.
___
"If you should need anything at all in the future, feel free to find me. I will do my best to help you, as plain "Lyney."
After learning the truth behind the twin's identity, Aether felt the need to distance himself from them until an interview lead to a delightful encounter between the traveler and the magician who wants nothing but his forgiveness and will do everything for him and the traveler to be alright again.
Working together to bring light to Cesar's case from years ago, will the two reconcile and discover new heights to their relationship or will they remain as they are now?

Going Back In Time To Make You Happy by Mitsuki_Sei

Summary
Set in a post-apocalyptic world, surviving humans were turned to cyborgs to survive. Everyday is a battle for survival where the strong predate the weak. Things were bland and dull for Aether. Surveying the surrounding area, scavenging materials, and collecting scraps before returning to the base.
That was his everyday...until he met Kuni.
From then on, his life became more interesting and warm. For a while, life was tolerable. He was almost happy.
Not until an ambush caused Kuni to protect him, even at the cost of his own life.
“On your scan, there was a heart icon.”
“fuck off.”
Aether looked at the gushing blood forming a pool on the floor. He stared at the man who's now on slower breaths. He grabbed his arms and put them on his waist.
“The base was more pleasant with you there.” Aether admitted.
Kuni's eyes trembled softly and gave a weak squeeze on the boy's hips.
“Feels less shitty, you know?”
“....” Only a tender look amidst his fading eyes.
“Don't leave.” The cigarette immediately fell from his lips and landed on Kuni's shirt burning a small hole, smelling like smoke and mint.
"If I could go back in time, I'll do my best to make you happy."
