That Night/Ragbros angst/No Kaeluc

Chapter 1

~Kaeya's pov~

"How beautiful"
I'm standing on top of Starsnatch cliff, a cup of wine in my hands (death afternoon, my favorite), gazing at the sky and stars. I stir the wine in my glass before taking another sip. Diluc... I can't stop thinking about all those souvenirs. Especially that night. That night when our father died. That night where he tried to kill me. That night where my vision appeared. That night where everything changed. It had to happened though. Even after all these years, I still ain't sure of where I belong. I know that Khaenri'ah is where my roots are but Mondstadt is where I feel the most at home. Well, "felt". I'm not even sure of what a home is anymore. Did I ever knew it? It seems that Diluc was right trying to exterminate me. After all, I am only but a spy of Khaenri'ah/the abyss order, Teyvat's enemy. Every act is in order to stop them and counterattack their plans. But they don't know the immensity of the thing. The pain. The horror of seeing all your loved ones turn into monsters, the feeling of being alone against the whole world. Even when you're at peace, you still have to verify everything, be cautious at every move and each word spoken. Sleep with ears wide open, an eye half closed. I've been taking every precaution and made sure that nobody knew. And yet, I still wish that this fate could have gone different...

~Diluc's pov~

'That's weird', I thought to myself. Even though it's his usual time, he still isn't there yet. And I know for sure that he would never miss an opportunity to go to the tavern and tease me.

-Huh, this feels strange drinking without Kaeya , right Rosaria?
-I must agree with you on that one Venti. It is much quieter. Not on the good side though.
-Don't you think so too, Diluc?
-It only makes less trouble to handle.
-Oh come one, he's your brother!
-He is not my brother.

Before Venti could argue back, Rosaria interrupted him, putting a need to this small verbal fight.

-But, Venti, do you perhaps know where he is? Wouldn't you happen to know something about it since you're always wandering around in the city.
-Oh, I heard he had a mission to handle and said that he would be back late. Ehe~
-Okay that's enough. The tavern is closing soon. Get out you two.
-Ugh, such a killjoy master Diluc!
-Get out.

~Diluc's pov~

While I was on my way back to the Dawn Winery, I searched for any sign of Kaeya, but it seems he wasn't back yet. It's already been a long time since he was gone, he should have been there. "This is just getting weirder", I mumbled to myself. Since I had arrived, Adeline noticed me. 
-Welcome back, master Diluc.
-...Hello Adeline
-Something on your mind? You seem distracted. Is it about Sir Kaeya? I heard he went on a long mission. I hope he's okay.
-It's nothing. I'm fine and I'm sure that he can take care of himself.
                   
                              ~In his room~

I look up to the wall, lying on my bed and see a painting. It represents young Kaeya and me with Crepus. "Father, Kaeya, I'm so sorry". A part of me wants things to be like back then. But I know it will never be possible. Father died and my "brother" is a spy from khaenri'ah. But....deep inside, I feel bad for trying to kill him and I would like to make up with him, even if I know it's probably impossible. "It's all my fault". "No, it's his". While I was arguing with myself, I noticed something that got me out of thinking. "Kaeya?" What in the archons was he doing here? I get closer to the window to see who he's talking to. He's injured and covered in blood. He doesn't look pretty happy. "He's not smiling anymore", I realized, shocked. Wait, is that a fatui with him!? There is also some abyss heralds, mages and a bunch of hilichurls. I'm too far to hear anything, but they seem to be dealing with a quite important matter, judging by the looks on their faces. Oh? The Fatui and abyss are leaving. What happened? Fuck, Kaeya is looking this way. He gave the dawn winery a last nostalgic look and walks away. What could he possibly be hiding...
