•Y/N POV•

I am sitting down under the waterfall cavern, it is so beautiful, waterfall is my favorite place at underground.
"Sannsss..."  I said to my bone-friend sans beside me. we are dating and today is our first anniversary.
"Yeah kitten ?" I can't help but blush at the nickname he gave me.
"Sans, when I am 21, I want to be your bride and be your wife" I said smiling at sans. Sans gives me a sweet grin and says,
"Okay then, I would love to be your husband" . We laugh together and throw puns at each other. Suddenly sans says
"That's a promise right ? you won't leave me, right ?" His expression suddenly changed to a serious one. I hug him and say
"Of Course, I promise!"  Sans' face softens a bit and we cuddle together until night comes

***

•Sans' POV•

It has been 4 years since our first anniversary and today I am just walking together with Y/N , hand intertwined with each other. I couldn't help but stare at her. She is just so beautiful, She has a sweet and kind personality and she is so energetic. Even though that she is 19 years old, she acts like an innocent kid, I love her so much, I want to protect her, I don't want to lose her smile.

•Y/N POV•

I was walking with sans when suddenly I felt pain shooting trough my body. My vision went blurry and I fell to the ground,
"Sans..." I called for him weakly. The last thing I saw was Sans' face and then I blacked out.

•Sans' POV•

I saw Y/N collapse to the ground and I caught her.
"Y/N ! Y/N please be alright, don't do this to me, I love you" I carried her bridal style and teleported to Alphys Lab. Alphys asked me what's wrong and she told me to put Y/N on the bed. When Alphys went to check on Y/N , I was crying, it hurts to see your loved ones just collapsed and fell unconscious.
Moments later, Alphys came out of the room, and said
"s-sans, Y/N got s-something human c-call 'A-anemia' " .
"Is she going to be okay ?" I asked her, tears still in the corner of my eyesockets.
"Y-yeah, s-she j-just need r-rest, I w-will find h-how to cure it. You c-can go visit h-her and t-take her home" With that, Alphys leave.
"Thank you Alphys" I sat up and walk into the room.
"Hey Y/N your alright ? Stop making me worry like that okay ? I love you so much".
"Heh.. I am fine ya bonehead, thank you for coming, so I won't be Bonely, hehe". She giggled at her pun, I smile and hug her.
"Remember your promise right ? never leave me" I kissed her forehead, she smile and cuddled with me, I pull her close and carried her bridal style.
"Let's go home , Shall we kitten ?". She laughed and screamed
"GO!!". We teleported to my bedroom and I set her at my bed. I pull off my jacket and slept beside her, sharing warm with each other.
"I love you Y/N".
"I love you too, ya Bonehead".

Since I knew about her anemia, I was taking care of her more carefully and everything went great until one day, it was her birthday, she's turning 20, we were walking together in a comfortable silence. I see Y/N with her adorable smile, her silver hair is flickering because of the wind, her blue eye shinning under the waterfall cavern. Until 'THUD' Y/N collapsed to the ground. I Remembered there is no sign about her anemia getting worse, and she was alright for a year, but why does she collapsed today after a year ? I already hoped that her anemia is gone, but why ? why does she collapsed again ? I want her to be alright until the end of my life.
I teleported her to Alphys lab and set her in the bed. Alphys took care of her. she said that Y/N need three or five days for recovery, I nod.
Every day I take care of her, I will feed her and we cuddle, Talking to each other,  every day I sleep beside her bed, taking care of her, watch her and protect her.

•Y/N POV•

I am very happy that sans is taking  care of me. I can see him every day, I smile at the thought. Suddenly I feel tremendous pain. It really hurts, I can't stand this. I called for sans weakly, but nobody could hear me. I am very weak now, I can't stand the pain, I am just going to write a letter for sans, quickly, I grab a paper and pen beside me and start writing, every word, I feel the pain is getting worse my mind roam and I remember all of the happy time I have been with sans, one more year I finally can be his wife, but I can't keep my promise, this pain is just killing me slowly.
After I was done I kissed the letter and I let out my last breath saying "I love you sans" and everything went black, finally I can feel peace and I don't have to bear the pain.

•Sans' POV•

This is the fifth day of my visit. I was just getting back from buying her a bouquet of blue rose, the same like her beautiful blue eyes. I walked into her room and saw her sleeping. I felt something is wrong before, but now I let out a sigh of relief 'Oh God, thanks, she is just sleeping'

But oh boy, was I wrong.

I checked her pulse breathe. I can't believe what I saw, there, I saw her, with her adorable smile, resting peacefully, her lifeless body rest with peace, I can feel my tears began strolling down my cheek. There, I see my once charming and energetic Y/N was no longer breathing.
"Hey, Y/N , don't play with me, this is not funny.. " I start to sob.
" Hey, Y/N you want to keep your promise right ? I really love you, I really am please keep your promise... i.. i.. one more year and I will take you to the church, I am going to marry you, hey Y/N, you can hear me right ?"  I sobbed and I hugged her lifeless body. I notice something in her hand, a paper.
I read the paper, I am getting hurter and hurter from reading her letter.

Dear Sans,

Hey Sans, Thanks for taking care of me when I was in the underground. I appreciate all of our happy times together. Maybe this is the time for me to go ? I am sorry I can't keep my promise. I can't stand the pain anymore I can't handle it, it was hurting me so much Sans. Hey I won't leave you, you know that right ? I willll alwayssss be there, in your heart, in everyone's heart :). I love you, I really am, always remember that ! Be good, alright ? for me. I love you sans,

From, Y/N

I sobbed, I cried, I hugged her lifeless body tighter. I couldn't tell what I should do. I couldn't bring her back. I am lonely now. Y/N meant world for me. Every day, we laughed together, I could see her adorable smile, all our good times flashed through my mind. I took her hand and kissed it, more blue tears started to roll out of my eye sockets. I could not hold it, it hurts losing your loved ones, it really hurts. I blamed myself, I blamed why couldn't I help her, why should she get that anemia, why couldn't I be by her side every second ? I felt useless.. I don't have hope anymore.
I felt something warm hugged me from behind, but nobody is there. I know it's Y/N. I heard a soft whisper
'hey, don't cry Sans, I am right here, I already said that,' I could feel Y/N smiling to me,
"I... I know sweetheart,"
'Then, smile for me won't you ?'
"Hehe, i... will... I am smiling now.. for you"
"I was late, wasn't I ?"
