Summary: Jiang Cheng is an alcoholic, while Wei Wuxian got into an accident two years ago and they're living together. Wei Wuxian has to help him, but he's close enough to snapping.

Sunkenly, Jiang Wanyin looped through the door, a mess of purple robes and missed hair. Wei Wuxian didn't have to look up to know his brother was full of lipstick marks, eyes probably too sore and too swollen to open.

"Welcome...back..." he slurred, walking lopsidedly as his head stung, almost as if it had been bashed in. That sent worry running through Wei Wuxian, as well as an innate frustration that left him sighing.

"What did you do this time, Jiang Cheng?" He asked petulantly, concerned, though there were slight undercurrents running through his voice, frustration directed at his brother. "I...did...nothing." The words swirled around in Wanyin's mouth like foamy alcohol, like a bitter joke against the coolness of the world.

Right. Nothing. Wei Wuxian continued sighing, running his fingers through his hair exasperatedly. He wheeled forward in his wheelchair, going forth to survey the true disaster his brother brought to his doorsteps. His brother's purple shirt was ripped, somewhat unbuttoned. His hair was messed up, his man-bun coming undone. The smell of alcohol clung onto him the same way the smell of sandalwood clung onto Lan Wangji, onto Wei Wuxian's own clothes, sickly sweet and tempting, but also revolting. The smell of it sent acid churning in his stomach up his oesophagus, and his stomach lurched at what he was going to do next. "Wanyin, go take a shower. " His voice was cold and authoritative, nothing like the one he used on him years ago, before.

"I don't want to.." he slurred, throwing his head back as he did that, perspiration running down his neck in trickles. "I don't need to."

Wei Wuxian continued sighing exasperatedly, and worry filled his eyes. It was days like this he hated the most, and knowing his brother was almost fully drunk terrified him in ways he couldn't comprehend. It was days like this, Jiang Cheng was the most unpredictable, when he could be unfailingly sweet, but was more often than not, nasty. Leaving Wei Wuxian to clean up after his mess, even with his wasted pair of legs. It was almost ironic, how only a few years ago it was Jiang Cheng promising him that he would take care of him. He could almost remember the older's earnest eyes now the tears that filled them when he said them, looking at the state the accident had left him in. How had things come to this?

"Go to bathe, Jiang Cheng. You need to." He struggled to keep his voice level, but the disappointment in his features was evident in his face.

His brother simply chuckled, choking on his laughter. He cocked his head to the side, mouth open and loose. His lips were dried and chapped, and the smell of alcohol filled the air again. It sickened Wei Ying, and he could feel vomit building up in his throat, the fear in his veins running like adrenaline. "No, I don't. What's wrong with you today?"

Wei Wuxian could barely make out his words now and his words seemed to blur together. "Go and bathe."

"No."
"Jiang Cheng."
"No."
"What's wrong with you, anyway? It's as if I did something wrong. "

This time, Wei Wuxian was the one who chuckled, laughing so hard his head rolled backwards. You did something wrong? As if you'd ever do that.

"What is it?" Tears welled up in Wei Wuxian's eyes, and he shook his head at his brother. I can't tell you. Not if I value my life. The bruises littering his arms were a testament to that, as well as the few scars he sported on his face. Most of them had faded into thin white lines now, safe for the red gash on his forehead.
"TELL ME! " Jiang Cheng shouted, infuriated. There it was, again. But Wei Wuxian had enough. "You really want to know? " He asked expectantly, locking gazes with his brother.

"I do! Just SPEAK already! " Jiang Cheng's voice boomed, sending reverberations of fear running through Wei Wuxian, along with a spark of anger.

He laughed bitterly, throwing his head back while the other stared at him in open shock eyes mixed with anguish. "When I'm away from you, I'm happier than ever," he whispered, his eyes never leaving Jiang Cheng's. Wish I could explain it better...he didn't...

"I wish it wasn't true." But every cell in his body was screaming for him to run to hit him or to yell, do something other than standing there and being stupid. But rage rippled it's way through his body, and he was held back only by the thorn of love that was embedded deeply in his heart.

"You call me again...drunk in your Benz, driving home under the influence. You scared me to death, but I'm wasting my breath," he glared at him, remembering nights spent pulling his half-paralysed body out of those to haul his drunk brother back from whichever club he lost himself to, always coming inebriated. The laughter of those that surrounded his brother like a group of magpies, the sly glints and bitter amusement in their eyes everytime he collapsed to the floor. "Cause you only listen to your fucking friends!"

A flash of fury blazed in Jiang Wanyin's eyes turning him into a monster that Wei Wuxian couldn't recognize. How have I been living with him? He lunged at Wei Wuxian, he gripped Wei Wuxian roughly by the shoulders before pushing him back, not caring if it hurt him. No, there wasn't a shred of remorse in his eyes as his brother's frail and wasting body thudded to the floor. Pain shot through his side, and for once Wei Wuxian was thankful that he couldn't feel his legs, not with the loud snap he just heard.

A red flush made its way to Wei Wuxian's cheeks, and shame filled him, as well as anger. This time, he didn't hold back, glaring directly at his brother. "I don't relate to you," he spat. If glares could slice, Jiang Wanyin would have been sliced a thousand times over.

"I don't relate to you, no. "

"Cause I'd never treat me this shitty! " He shouted, not caring how badly it hurt. Adrenaline rushed through him, and he didn't bother filtering the words that came ahead.

"You made me hate this city! "
" And I don't talk shit about you on the internet, never told anyone anything bad," his grey eyes slitted close, his voice filled with more venom than Jiang Cheng could remember. Visions of the last texts he'd seen on his brother's phone flashed before his eyes, bringing more tears to his cheek as his heart ached. The sound of raucous laughter directed at him, when they thought he couldn't listen. I might be half- paralysed, he thought, but I'm neither dumb nor deaf. "Cause that shit's embarrassing, you were my everything, " I'd have given anything for you.

"And all that you did was make me fucking sad. "

" So don't waste the time I don't have, and don't try to make me feel bad," I spent three years trying to save you.

"I could talk about every time that you showed up on time, but I'd have an empty line, because you NEVER DID! '' Tears streamed past his face now, as he recalled nights spent idling in class, waiting for a brother who'd never come. No, Jiang Cheng was always too busy. And Wei Wuxian didn't mean anything to him. Nothing at all. He looked at his brother with renewed vigour, even as sobs wracked his body. Jiang Wanyin looked thoroughly shocked, as if he'd never expected to be berated like that. And maybe he hadn't, given how Wei Wuxian had been trying to please him and step around him. It sickened him now the butter taste of bile pushing past his lips.

"Never paid any mind to my boyfriend or friends so I shut them all out for you cause I was a fool. " Tears streamed past his face in rivulets now, exhaustion from staying up starting to press down on him.

The pain in his back dulled, and his senses seemed to be shut off as he continued on.

" You ruined everything good. Always said you were misunderstood." He played with the word, twisting it in his mouth viciously with a half-hearted smile. Jiang Cheng's mouth was agape, fury starting to line up with his eyes, mingled with regret. Wei Wuxian savoured the regret, but he highly doubted anything would even change tomorrow. Jiang Cheng would just go back to being drunk. He wouldn't remember a thing the moment his head hit the pillow.

"Made all my moments your own, " he spoke softly now, his voice barely above a whisper, though he knew Jiang Cheng heard him, the bitterness engulfing his voice.

"Just fucking leave me alone." The words hung over his brother like a guillotine, and fell, the final blow to his head. They were uncharacteristically harsh, then again Wei Wuxian was more than sick and tired of his antics. He cried bitterly, not caring for the torrent of pain that came after, his vision blurring with tears before he fell back to the floor, encompassed by blissful darkness.
