Kaeya always remembered you coming and going in their childhood, and he never questioned it. After all your family wasn't living at the winery, just close friends with his adoptive father. He also remembered always having one of the parents keeping a close eye on you three of you.
Today your parents were speaking with their father in private while you sat outside and watched the boys spar with their weapons.
Kaeya looks over to you and smirks, "Would our princess like to learn to wield a sword?"
"Kaeya, don't force her-" Diluc starts, but is cut off by you.
"I doubt a sword is my style. Plus it's more fun watching you boys play." You call out from the tree you are sat under.
"Oh, what happened to that little girl antsy to keep up with me~" Kaeya teases.
Just then your mother calls out for you all, so the boys sheeth their weapons. Kaeya helps you off the ground and the three of you head over to your parents.
Your mother is the first to speak, "Y/N, your father and I are headed to Liyue. We will be leaving you under Crepus's care for the week we are gone."
"Alright, please be careful." You say and look to the boys who are thrilled.
With that they get on their horses and head off.
Crepus smiles at you three, "Lunch will be in an hour, why don't you three keep busy until then."
The three of you agree and head over to tables to sit.
Kaeya speaks up first, with curiosity, "So why are they headed to Liyue?"
"Oh, well, to look for something for me. Nothing too big. Just something they'd been planing for a while now." You shrug it off then smile, "How about the Knights? How is that going for you?"
The boys share a look before accepting the topic change.
The first three days turn out to be uneventful. A routine is quickly found and the boys are completely amused with how their father seems to dote over you. They are convinced that if he had a daughter, she would be spoiled just like this. They never once pick up on the slight discomfort you have when up for too long or the fact that every day you've taken a nap half way through the day. Then again, you've always been one to hide your pain with a smile.
The afternoon of the third day, you had awoke from your nap to the sound of Diluc and Kaeya coming home.
Diluc smiles to you, "Where did father go?"
"He said he had a meeting and would be back for dinner." You relay the information and sit up.
"And just when we were hoping to bother him. Shame." Kaeya says with a playful smirk.
You roll your eyes at him with a smile, "It's a nice day out. I was thinking we could go for a walk?"
Diluc nods, "Sounds like a good idea. Though you didn't have to wait for us to do that."
You feign shock, "How could I ever go out without you two?"
Kaeya smirks, "A damsel always needs her Knights in shinning armor; is that it?"
Diluc rolls his eyes, "She is hardly a damsel. Too witty."
You giggle and get up from your spot on the couch, sliding on your flats, and heading to the door. A short while later and the three of you have made your way farther out than you had ment to go and are at the riverbank. Diluc looks around skeptically, "This area is normal not watched by the Knights. We should be cautious."
Kaeya only shrugs, "We are Knights. It will be fine."
You look between them and sigh, "We can start heading back. I'm just happy to have been out and about. Not often that I see the land."
"Why is that?" Kaeya raises a brow at you.
"Well I do live in the city." You offer up the excuse and turn to start walking back to the manor.
"That doesn't mean you couldn't go for walks on your own." He comments as they follow behind you.
You shrug with a sigh, not noticing the glance the boys share with eachother. You do notice how your legs are starting to feel numb and your head is starting to hurt. This would be why you never went on walks alone. You crave to see the world like they do, but this unusual disease that is griping your fragile body won't let you. And today you just had to loose track of how far you'd gone. The last thing you wanted was for your best friend and your crush to see you as weak. Feeling weak is one thing, but to be looks upon as weak is a whole other feeling. And lately you've only been feeling weaker by the day. It's why your parents left for Liyue. To bring the new doctor they have here to look you over.
Suddenly your legs shake and give way from under you. Kaeya is quick to jump to you, catching you in his arms. "Y/n... are you alright?"
"I am... just need to rest..." You mutter, clutching to his clothing weakly.
Diluc looks worried at you, "Please don't hide anything from us. What's going on?"
You look at the ground, "I have a rare disease of sorts... the church isn't able to do anything except help ease the pain and slow its progress... that's why my parents went to Liyue. To find that new doctor in hopes he can help me..."
Kaeya carefully moves to sit on the ground and hold you on his lap, Diluc following suit and moving to sit as well. Kaeya then asks softly, "You say to slow it... do you mean this could be a fatal disease or...?"
"It seems to be that way... I'm sorry..." You mutter out without looking up.
Kaeya seems to hold you a little tighter as Diluc speaks up, "Don't be sorry. We are here to help in any way. Your still our friend that we grew up with."
You look to him and only see sincerity and comfort. When you look to Kaeya you see see sincerity as well. You can tell they don't see you any differently, but at the same time seem worried.
Kaeya finally speaks up, "Lets get you back to the manor. I'll carry you."
After that, the boys didn't treat you any differently but did understand why their father was always checking on you.
The next day, you end up curled up on the couch and sore. Kaeya sits by your side, helping the maids in caring for you. Unexpectedly, there's a knock at the door. Diluc and Crepus come out of the study and answer it while you and Kaeya watch from the couch. After a brief exchange with the stranger, the two shut the door and come in looking solemn.
Crepus speaks first, "There's been an incident. Your parents never made it to the Harbor."
"What do you mean? Are they back home?" You sit up straighter, your world suddenly feeling smaller.
"Some adventurers in Liyue found them too late... the church is already making preparations for the services..." He starts to explain delicately.
You however lose focus, your world shattering. Kaeya pulls you to him gently as sobs wrack your body.
You and Kaeya had moved into your parents home not long after Crepus had passed. He and Diluc were on the worst of terms and you had no idea as to why. Kaeya wouldn't even speak of what happened to you. All you knew is that they had a really bad fight and he managed to get a vision.
Today was one of your better days, as your health had become worryingly worse over the years, and Kaeya was greatful for that. Today was also the day Diluc was supposed to be returning from finding a doctor to bring back to see you.
It worried you sick to see your friend go on the journey that stole your parents from you, but you knew Diluc was more adept to the hardships the world could throw at him.
Kaeya sits down beside you and holds your hands in his, "Y/n?"
"Kaeya?" You look to him questioningly.
He smiles gently, "Whatever happens today, whatever the doctor says, I won't leave your side. You know that right?"
You smile gently at him, "Why would you ever leave me?"
"Why indeed, my snowflake." He smiles charmingly at you.
You can't help the blush that raises to your cheeks.
The knock at the door interrupts the moment, and Kaeya answers it.
Soon you are being looked over by a doctor with a dendro vision and before you know it Diluc, Kaeya, and you are sat down to hear what he has to say.
"Well, the good news is I've seen this once before. And I can treat it." He explains.
Diluc skeptically leans forward, "You say that as if there is a downside."
The doctor merely nods, "I cannot restore you to the full health you were once in."
You nod, understanding what he means. You had been relying on Kaeya to walk for a few months now.
Kaeya speaks up, "What is this treatment exactly?"
"I'll provide you with the recipe, its a daily supplement she will need to take. Give it a week to see improvements. After two weeks you will be at the healthiest we can achieve." He explains moreso to you than the boys.
"So my strength should come back some..?" You ask nervously. You just don't want to be a burden to Kaeya or Diluc any longer.
"To an extent, yes." He confirms.
Kaeya and Diluc share a smile for the first time in a long time and look to you. You sigh in relief, "Then I'd like to start it."
"Of course." He says and hands over a detailed recipe that is shockingly all locally sourced, "Your lucky to be here, the last patient had to have the ingredients sent all the way to Fontine from here."
Kaeya smiles, "Thank you. This is great news."
Diluc nods in agreement and looks to you, "I'm glad this was a good resolution. I'll be back in three days, I agreed to ensure the doctors return home was safe."
"Be safe yourself Diluc." You smile up at him as he stands, "And thank you for this."
"Anything for you." He says gently before taking his leave.
Kaeya wraps his arms around you happily nuzzling his face into the crook of your neck, "I'm glad we could get you what you need..."
You hold to him and giggle softly, "I always knew I could count on you two... and thank you for taking care of me all this time."
He kisses your cheek, "of course my snowflake"
