Fic I thought of but will probably never write

The star twins are actually triplets. In the last world where all three were together, the youngest had grown attached to the inhabitants and helped nurture a growing civilization that, if left alone, would cease to exist. But the triplets were beings that never stay in one place for too long. The call of the stars and the worlds beyond are too strong to ignore, but the youngest's compassion and nurturing nature overpowered that call.

She didn't want to force her siblings to stay as she helped the civilization to flourish, to ensure that they'll be able to stand on their own without her guidance, to ensure their future is secure. So she told them that she will catch up to their journey.

Aether and Lumine didn't want to leave their sister behind. Their very souls ached and cried at the thought of separating from her. They argued, almost to the point where they wanted to force the sister to leave with them. But the third insisted and, with plenty of promises and reassuring their worries, they finally relented.

When the second triplet sister accomplished her mission, she set out to find her siblings. After a long journey, she finally pinpointed their location, in a world called Teyvat.

"Brother, sister, I'm finally coming home to you."

Meanwhile...

A beat. A strong and familiar energy washed over him. Something in his soul shifted. A vacant space that suddenly stirred to life and completed the puzzle that was his very existence. His whole body, his heart, mind, and soul calling out to their third, to their triplet sister who has been away for so long.

Aether froze, hand flying to his chest as he felt the bond that felt so far away and so painful, like a rubberband stretched thin, now easing and coming closer.

His gaze moved to the fake sky above and if he tried, he can see a dazzling shooting star heading straight to where he is at.

She was coming home.

Orrr...

Aether is a siscon who desperately missed his two other halves because one is an Abyss ruler and the other one has been a civilization's ruler/saintess who is prone to reckless actions. One is actively avoiding him until he finishes his journey and the other is finally returning to his side. And he will ensure that's where she'll stay.

Now this is a setting where everyone is obsessed with Aether but he never seem to reciprocate, notice, or understand their advances. Then come his second sister that popped out of nowhere who effortlessly got all his attention, love, care, and doting.

At first, the admirers were jealous of the biased treatment. But then they see how compassionate, loving, nurturing, and understanding she is. She is also a BAMF.

Now almost everyone is also obsessed with this girl who is mildly aware of their advances but can't be bothered to deal with it. She just wanted to be with her brother while they look for their sister.
