I have needed BSD sickfics for so long you have no idea I just need them so much but Mafia!Dazai and Alive!Odasaku and mafia!Ango with Dazai catching something from like, Chuuya or something (and gets completely run over because he rarely gets sick) cue dark fever dreams and Oda caring while Ango.. is Ango?
Dazai, Oda and Ango walking home from the bar together was recently becoming a more frequent occurrence. On these nights, the trio simply couldn’t get enough of each other. They wanted to exchange more stories, complain more about anything wrong with their day, or even just give their opinions of random, obscure topics. While Oda and Ango always rolled their eyes at Dazai’s antics, they often found themselves looking forward to seeing him again, not that they would ever admit it. That was why, on the night Dazai stopped pestering them, Oda was immediately confused and startled.
“Take my coat,” Dazai ordered quietly, draping it over Oda’s shoulders before continuing to walk home in silence. There were obvious gaps of silence where Dazai would usually jump in with something witty or plain eccentric. Instead, it was just Oda and Ango chatting quietly. Was this really Dazai they were walking with?
“I feel dizzy.” Dazai announced suddenly, and the other two men looked at him in surprise as they walked. It would explain the silence, but it seemed impossible. Dazai never got sick. He had jumped into countless rivers in shockingly cold weather and come out grinning. No amount of sleep deprivation could dent his immune system. To put things simply, Oda believed Dazai was playing a prank on them…. until he swayed, and fell to the side.
Ango dived forwards and Dazai landed neatly in his arms, falling limp and silent. At first, they were both silent. Then the panic set in. “What just happened?” Oda demanded in confusion. “Dazai is unconscious in my arms, that’s what just happened!” Ango snapped frantically, staring down at Dazai with a mix of repulsion and concern. “What do I do!?” “We should probably get him home.” Oda replied, already calmly putting a plan together to help his friend, who was clearly unwell. When Ango didn’t move from his crouched position, still cradling Dazai in his arms, Oda took Dazai from him and began walking in the direction of his friend’s apartment. Ango followed, watching the unconscious boy in disbelief.
“You don’t think he’s sick, do you??” Ango wondered nervously. A sheen of sweat gleamed on Dazai’s face and upon closer inspection, his cheeks were pink and flushed. “I think he’s sick.” Oda confirmed. He was sure he recalled Dazai laughing earlier about one of his coworkers fainting in a similar fashion to this. “He probably caught it from that Nakahara Chuya guy. They’ve been spending too much time together.” “You sound like you’re jealous of him!” Ango scoffed, but his laughter had a slight edge to it as he continued to glance at Dazai. Although he didn’t act like it, he was probably worried deep down. “Jealous!? Of course not!” Oda cried, and then added a quiet “Maybe.” after.
By the time they got to the apartment, Dazai was definitely looking worse than before. Oda gently laid Dazai on his bed and, upon feeling his burning forehead, carefully removed his tie and unbuttoned his shirt in attempt to cool him down. Ango brought in a cloth soaked in cold water, but tried to hand it to Oda instead. “I’m not putting my hands near him! That thing is contagious!” Ango hissed, reeling back as soon as Oda took the cloth.
Oda spread the cloth over Dazai’s forehead and patted it down for good measure. The coolness of it seemed to have given Dazai some relief, because he was beginning to stir a tiny bit. “Dazai, can you hear me?” Oda called curiously, but his only response was a soft moan. A few seconds later, Oda noticed Dazai’s lips moving, but if he was speaking it was too quiet to hear.
“….sh…” Dazai finally uttered at a barely audible volume. “What was that?” Oda inquired, leaning closer to his friend. He waited, listening eagerly for anything, maybe a request for water or to open the windows. Oda was startled by a loud clank beside him instead, and jumped when he noticed Ango moving a chair to Dazai’s bed.
“Finish it….” Dazai murmured, and Ango scoffed. “He’s delirious.” Ango sat down and flicked open a small lace fan, which he proceeded to fan Dazai with. It was a small gesture, but somehow Oda found it touching to see Ango making an effort to help lower Dazai’s ridiculously high temperature.
Oda and Ango stayed by Dazai’s side for an hour, occasionally making small talk but mostly focusing on Dazai’s sleeping form. His chest rose and fell rapidly, uttering tiny inhales and sighs. It was strangely heartbreaking to see Dazai so weak and vulnerable. Oda knew that if he could have it, Dazai would never turn to him for this kind of help. If the fever hadn’t kicked in until Dazai arrived home, he probably wouldn’t even call Oda for help, and no one would ever have known he was sick.
The next time Dazai moved, it was tossing and turning. By then, his temperature was fluctuating, switching between hot and cold every few minutes. “He looks really cold….” Ango observed in concern. With a simple nod of agreement, Oda tucked Dazai into bed. Dazai whimpered softly, and squirmed uneasily beneath the blankets. Oda wondered for a second if Dazai was actually hot, but he was shivering way too much for that to be the problem. However, he instantly understood what was going on when Dazai began thrashing and pushing against the blankets, yelling and….
“Is he crying!?” Ango demanded in surprise. Oda immediately began shaking Dazai awake. He thought he had seen enough of his friend suffering from the moment he fainted, but to see Dazai so terrified and upset was the last straw. “Dazai, Dazai, it’s just a nightmare. Wake up now. You’re okay.” Oda soothed, watching his friend in concern.
Just like that, for the first time that night, Dazai’s eyes fluttered open. They were glassy and unfocused, almost seeming to stare over Oda’s shoulder instead of at him. “Ah….” Dazai swallowed and cleared his throat, blearily taking in the reality of the situation. “Oda…. I had this dream where you were shot….”
Oda blinked at Dazai in surprise. Surely his memory was too foggy. Would Dazai be that scared about Oda dying? “Promise…. promise me you’ll never…. get shot….” Dazai begged deliriously. Oda used the cloth to brush back Dazai’s damp, matted hair, and took Dazai’s hands into his own. “I promise.” Oda laughed, smiling at Dazai reassuringly. Slowly, weakly, Dazai smiled back and his eyes fell shut as he drifted off to sleep again. Oda felt at ease almost as much as Dazai must have in that moment.
