FlowerFell!Sans X Sick Reader

The other night dear, as I lay sleeping
I dreamed I held you in my arms
But when I awoke, dear, I was mistaken
So I hung my head and cried

Sans started to let the red tears fall down his face and his eye lights went out. His forced smile turned into a sad small smile.

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away

Sans laid his skull in his hands and sobbed quietly.

I'll always love you and make you happy.
If you will only say the same
But if you leave me and love another
You'll regret it all someday

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear how much I love you
Please don't take my sunshine away

You started to have tears run down your face and your smile filled with heartbreak.

You told me once, dear, you really loved me
And no one else could come between
But now you've left me and love another
You have shattered all of my dreams.

You started to cough slightly but you held it back with all your might.

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away

In all my dreams, dear, you seem to leave me
When I awake my poor heart pains
So when you come back and make me happy
I'll forgive you, dear, I'll take all the blame

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away.

You collapsed to the ground and coughed up all the blood and petals you were keeping down. Sans lifted his skull quickly and looked down at you in horror. He hurriedly got out of his stand and picked you up and brought you to his house. When you both got there he sat you on the couch and pulled out his phone with a shaky skeleton hand. He teleported out of the room and to his room. You sat on the couch looking around the place with clouded, lazy eyes. 

Sans was in his room on the phone with Alphys. Alphys told him she was on her way over and will be over as soon as possible. He came downstairs slowly and still shaking. He kneeled in front of you and asked how you were. You gave him a shaky, "I'm okay, no need to worry." You coughed slightly and then closed your eyes to catch up on some sleep.

When you woke up you see Sans and a lizard lady, you assumed this was Alphys, talking. You slowly and carefully sat up and rubbed the sleep from your eyes. Sans told you what was going to happen. You agreed and went with Alphys back to her lab. 

She diagnosed you with Hanahaki Disease. 

You get it when it's a one-sided love, you start to have flowers grow inside your lungs and start to cough up the buds and petals. Once your lungs are filled up you die from choking. Alphys led you into her lab and had you change into a nightgown. She started to hook up machines and started to do tests on you. You're pretty healthy aside from the disease.

6 months later...

Your disease only got worse there were now flowers covering your legs and upper torso, it was hard to breathe. Sans would visit from time to time but didn't say much except, "Flower you today, Sweetheart." You enjoyed his company and wanted to tell him how you felt cause over time you fell in love with the punny skeleton. But that only made the disease worsen. 

You woke up in the middle of the night feeling the need to throw up. You slowly get up and stumbled to the bathroom. When there you quickly kneeled in front of the toilet and threw up your dinner, blood, flower buds, and petals. 

You felt someone hold your hair back and you smiled grateful for their help. 

Finishing up, you turn around and see Sans standing behind you. You reach out to him and he quickly kneels in front of you. Hugging him he hugs back like you would disappear if he let go, not like it hasn't happened before. He heavily sighs into your shoulder and says, "Listen, Sweetheart, I have something to tell you." You nod your head telling him he can continue, "I love you... I'm so afraid of losing you. I don't want you to die. I love you so much, Sweetheart." You start to cry into his shoulder and hold onto him for dear life. "I love you too, Sans. I don't wanna leave you and everyone else behind. I don't want to make you all upset." You both cry into each other's shoulders while whispering sweet nothings into each other's ears.

In the morning, Alphys came into the lab and saw you and Sans talking. She smiled but had to do your daily tests. Sans excused himself and let Alphys do her work. You got done with tests and asked Alphys how fast it was going this time. She frowned but answered anyway, "You don't have long to live, it seems with the rapid growth of the flowers. It's increased by a good 5% since the last time we tested you. But you have a good two years before it fully takes over your body and you become nothing but flowers in the wind... Just like Frisk" She mumbled the last part so you couldn't hear. 

You sigh and told her that Sans should know. Alphys walks out of the room and talks to Sans. He came into the room with a grim look on his face. A shadow was covering his eye sockets and he came up to your bed and hugged you. You hugged back. Afterward, he proceeded to tell you that he wants to treat you. You agreed to it and Alphys helped you. 

When Alphys finished helping you doll up you came out in a blue dress shirt, long black skirt, and black flats. Your hair was braided and you had a small pearl hair clip. Sans took your hand and teleported you to MTT Resort where you both had dinner and then he teleported the both of you to Waterfalls. He walked with you as you both say sweet nothings. 

When at the top of the waterfall you looked out and into the black abyss below. It was so scary but you didn't want Sans to be sad anymore. Telling Sans to close his eye sockets you walked up to him. You kissed his teeth and whispered into his nonexistent ear, "I love you, Sans. You're my sunshine but your Sunshine is being taken away." You walked up to the edge of the falls and told Sans to keep his eyes shut, but you knew he wouldn't listen. 

You jumped. He fell to his knees and cried. 

Falling into the black, never coming back.

But who is here with you?
