One day in late august around midnight, Chuuya is woken up by his partner groaning in pain. "Hey, Mackerel" he whispered "You okay?" Dazai doesn't respond, he just continues to whimper and Chuuya can feel him curl in on himself. Actually somewhat worried now, Chuuya sits up and turns to face Dazai. "Osamu-" he starts, but he pauses as his eyes somewhat adjust to the darkness. Dazai's face is scrunched up, his hands are pressing into his forehead, and his body is curled up extremely tightly. "Hey, Osamu" Chuuya says softly as he brushes his hand over Dazai's back, rubbing in comforting circular motions " What's going on? Are you hurt?" Dazai groans before whispering so quietly that Chuuya almost can't hear him "...head...hurts" Chuuya frowns "You got a headache?" Dazai nods slightly before freezing up and clutching his hands to his head harder. "Hey, hey, don't move so much" Chuuya murmurs. "Is there anything I can do? Anything you need?" He asks. Dazai is silent for a moment before he whimpers back "...'m thirsty" " Alright, I'll go get you some water." Chuuya rubs Dazai's shoulder for a second before standing up and going to the kitchen to get his partner a glass.
When Chuuya returns with the water he notices that Dazai has started hugging a pillow with one arm, his other hand tugging at his hair and seems to be... shaking? He walks closer, slowly sitting down on the bed, so as to not jostle him too much, and rubs his back. " Mackerel, darlin', I need you to sit up for me." he whispers. Dazai groans in protest but eventually, he sits up, wincing. Chuuya holds the glass to his lips and slightly tips it back, being careful to not pour too much and have Dazai choke. Once Dazai drank about half the glass, Chuuya set it down on their nightstand (on a coaster of course) and turns back to face Dazai, rubbing his arm. "Do you need anything else? Want me to go to the store and get you advil or asprin or something?" Dazai just slightly shakes his head and tugs at Chuuya's sleeve. " lie down chibi.." Dazai murmurs. Chuuya, slightly confused, does as he asks and lies down. Dazai slowly lies down on top of him, head smushed against where Chuuya's neck meets his shoulders, wraps an arm around his waist and grips at his shirt with his other hand.
Chuuya rubs his left hand over Dazai's back while his right starts lightly stroking his hair. He's careful not to press too hard as he starts massaging Dazai's head, hoping to help relieve the headache somewhat. "This okay darlin'?" He asks, smiling slightly when Dazai whispers a "..yeah". "Are you sure you don't want any headache meds?" Chuuya asks. "..no just, just wanna sleep" Dazai whispers back. " Alright" Chuuya says, kissing the crown of Dazai's head "sleep well darlin' " Dazai hums back something reminiscent of a "you too" and starts snoring.
Chuuya stays awake a bit longer, still stroking Dazai's hair, rubbing his back, and occasionally pressing kisses to his head. He just lays there, on his back, staring at the ceiling, and enjoying the warmth of his partner on top of him, how Dazai holds tightly onto him as if he never wants to let go, and slowly feels his eyes get heavier and heavier, his hand on Dazai's back slowing down even more. His breathing starts syncing up with Dazai's, his eyes finally close, and he drifts off into a warm comfortable sleep.
