Promise Me That You'll Be There (aftercare)

Summary:

Whether he's nine and spasming with each gag as he vomits into a bucket by his bed, hairs standing on end and a sharp burning in his stomach, only comforted by the gentle pressure of his mother's hands stroking his forehead or sixteen and having a friend shove their fingers down his throat to make him throw up the pills he's just swallowed, cold tile underneath him seeming to freeze him from the outside in, hair clinging to his sweaty forehead and drool sticking to his chin and dribbling down his neck.

Dazai Osamu has a complicated history. It sucks, it really really does. That horrible burning sensation in his throat, rough and scratchy when you dribble bile into a toilet and how strange it smells… but, I don't know, it's silly but he almost finds it to be purifying.

He always feels reborn when he's sick, cleansing his body from the inside out. Getting rid of sticky, heavy lard lodged inside of him and tainting what could be perfect and right now Dazai needs pure.

 

Dazai Has A Complicated Relationship With Vomit – or the agency tries uselessly help out their new, bumbling blind co-worker with his disturbing secret.

Notes:

Title from Aftercare by Nessa Barrett

This is a short one I'm somewhat ashamed but I haven't finished any of my other fics yet and I'm just soo excited to post!

I want to clarify that this is just me rambling about how I feel and how disgusting throwing up sweet things is but everything is dramatised to match Dazai as a character. I am portraying him to have an eating disorder because I think It really fits with his character but I personally do not have an eating disorder and haven't done enough research on them yet. If you notice any inaccuracies please lmk and I always appreciate constructive criticism but this is a throwaway rant fic to bear that in mind lol

If you see any spelling errors no you didn't I wrote this chapter in like 45 mins pls don't shoot me

(See the end of the work for more notes.)

Chapter 1: Before Work

Summary:

edit: i changed the spacing and added like two scentences. I wish i wrote this longer but i don't know what to add. It's probably far too late no anyway. I am somewhat in the process of writing another chapter. I have one chapter fully written but it's not in the order i want so i'll hate to write one before it and i have like no ideas lately.

Alsoalso! I'm so obsessed with olivia rodrigo's new album, purple is soo skk coded and i haven't seen anyone connect those imaginary dots yet. I think i said that on my twitter but i'm basically like lois griffin posting "well THIS happened" if you know what i mean.

Chapter Text

Dazai has a very complicated relationship with vomiting.

Sure, everyone does, but this is a long complicated relationship, more of a marriage than anything.

Whether he's nine and spasming with each gag as he vomits into a bucket by his bed, hairs standing on end and a sharp burning in his stomach, only comforted by the gentle pressure of his mother's hands stroking his forehead or sixteen and having a friend shove their fingers down his throat to make him throw up the pills he's just swallowed, cold tile underneath him seeming to freeze him from the outside in, hair clinging to his sweaty forehead and drool sticking to his chin and dribbling down his neck.

 

Dazai Osamu has a complicated history. It sucks, it really really does. That horrible burning sensation in his throat, rough and scratchy when you dribble bile into a toilet and how strange it smells… but, he doesn't know, it's silly but he almost finds it to be purifying. A holy act of devotion to his own sick need to perpetuate his own suffering.

He always feels reborn when he's sick, cleansing his body from the inside out. Getting rid of sticky, heavy lard lodged inside of him and tainting what could be perfect and right now Dazai needs pure.

Knuckles aching red raw and fresh bruises blooming on his thighs from his tightly he's gripping them, hunched over in his shower at ungodly hours trying to flex his stomach to just get it all out, he swears he can still feel something in his stomach just waiting to be freed.

The raw, abraded skin of his knuckles does comfort him deep down. When he was a child his mother would always call the fresh skin underneath a healing scrape his “baby skin,” and would kiss the pinkish skin of his knees or arms or face after he’s fallen over to “help it grow into big and strong skin.”

He often wishes that he could be made out of “baby skin” that needs to be kissed better, and he’s tried. Every futile attempt to rip open his skin, sobbing into his pillow wishing for his mother to come and find him here, to kiss away the hurt and soothe him back to sleep but Dazai isn’t a baby anymore and that woman is nowhere to be found.

 

The spray of water is uncomfortable, spurting dizzyingly hot water all over his face and fingers. Thick globs of salvia dripping down to his elbows and splitting against the porcelain.

Everything is so nauseatingly wet, teeth still sore from the cold water he's just chugged only a temporary distraction from the horrid gurgles in his stomach.

He really wished he was quiet during this.

The noises are the worst part. Like a sick sense of eroticism creeping into everything he does. It only serves to make him feel worse, the harsh spray of hot water on his back turning almost painful as water taints his freshly styled hair and drops down his neck.

Any semblance of pretty sinking down the drain along with the chunks of watery vomit.
Ice cream tastes sickly sweet coming back up, almost just as good as the first time. Tainted by the bitter, acrid taste of stomach lining.

Almost

Dazai finally gives up and turns the water off when the ache in his stomach from gagging gets to be too much. Not even bothering to dry off before unlocking that special room in his one bedroom apartment.

Untouched, pure. Left just as he left it, haunted by the ghost of the man who changed Dazai's life. It’s almost like a museum, Dazai always feels like a monster walking into this room.
Filthy, slimy, horrid. He sinks onto the floor, chest flush to Oda’s duvet covers, and closes his eyes like a prayer.

God, he doesn't want to go into work tomorrow.
