Setting: In Miya Atsumu and Osamu's shared room at around midnight. ( Osamu's POV )

I'm so exhausted, I can't even move from my bed . After school practice was a livin hell, all we did was runnin and jumpin skills.

Tsumu passed out when we got home. I just did his homework for him. Suddenly my thoughts are interrupted by a harsh cough comin from above me.

"Tsumu ya good?" I ask

" Yah I just choked on my spit." Atsumu replied in a scratchy voice

" Sure ya did." I say sarcastically

Whatever, I'm too tired to care.

~ Time Skip Next morning ~

Stupid Tsumu is still sleeping and school starts in 15 minutes.

"Get up, Tsumu we're gonna be late!" I say

He just mutters and shifts. I literally hafta drag him outta bed and splash water on his face for him to wake up.

This is unusual, usually I only have to tell him a few times. Maybe it has something to do with the coughing last night.

~ At school ~

During our first class Tsumu looked half dead. His face was pale and his eyelids droopy. Every once in awhile he will break into a coughing fit

"Tsumu yer not okay you needa go to the nurse or something." I whisper to him

" I'm fine I'll just take medicine during lunch, If I go to the nurse they might send me home and Sunarin can't tutor me later" he replies

" Sunarin, is tutoring ya?" I ask suspiciously

~ Flashback Yesterday During lunch Atsumu POV ~

I can't believe I flunked that exam. I studied so hard last night that Samu had to tell me to go to bed, and I'm usually the first one in bed.

I need a tutor and fast. The first smart person I can think of is Sunarin. He's smart and always gets good grades.

I go to Sunarin's homeroom class where he always eats lunch. My plan is to secretly ask him to tutor me.

"Oi Sunarin ya know yer really smart, I feel like it would help so many people if ya shared yer knowledge. I said

"Atsumu, just ask me to tutor you like a normal person would." Suna said bluntly

"Yah I need the help I can't afford to fail another exam please please please please," I plead desperately.

" Fine, but you have to follow the exact time I give you and be quiet while I'm teaching you." Suna said

" Thanks so much you saved my life Suna!" I yell running back to the lunch room.

~ Back to the present Osamu's POV~

" So yeah I can't not get tutored today or else suna might refuse to do it tommorow." Atsumu finishes

Fine if he wants to stay at school while he's clearly sick then I'll let him. After class ends we head to the lunch room where 'Atsumu Fan Girls' automatically start crowding 'round Tsumu like he's a magnet.

"Miya-san I saw you practicing after school yer so good at setting!" squealed a first year girl.

"Atsumu- kun your hair looks so nice today" a third year girl commented.

Tsumu was sweaty and looked like he was hyperventilating. I knew I was gonna have to save him.

"Tsumu, can you help me find my pencil case in the classroom?" I lie

" Sure " He said relieved

~ In the classroom ~

" Thanks Samu." Atsumu said

Yah don't mention it, but if you need my saving one more time today i'm forcing ya to go home"

I tell him

" Fine." he said

~ After school volleyball practice ~

" Atsumu, stop being a lazy ass and hurry up!" Aran screamed from the edge of the court.

" I'm coming, I just needa tie my shoes." Atsumu replied leaning on the wall.

Once practice starts, Tsumu's movements become slower and slower. After about 10 minutes he can't even react fast enough to set.

Akagi ( the libero) passes the ball to Tsumu and it hits him smack dab in the face. The next second he faints and falls to the ground

The entire gym goes silent.

"Tsumu !" I yell

Everyone crowded around him. My heart starts beating so quickly I felt like throwing up.

No! No! No! Why didn't I just send him home when he was sick earlier

I run to the locker room to get an ice pack to cool him down. I shake him and shake him and he doesnt get up. Everyone is worried and trying to calm me down.A few frantic minutes later he opens one blurry eye and looks at me confused

" What happened ? he said confused

" What happened, What happened? You made me almost have a heart attack because you're so stubborn that you can't just do something when I tell you to. I love ya Tsumu. I don't know what I would do without ya." I say as tears stream down my face.

" I'm sorry Samu, I'm sorry I made you worry so much, I love ya too I mean you are my twin after all." He replies

I just smile, and Kita and I help him up from the ground and sit him against the wall.

"I'm going to call ma to pick us up and don't move till she gets here." I demand

"Don't worry I won…." he says starting to doze off

~ About 10 minutes later Mama Miya arrives ~

"Oh my baby" She says running over to Atsumu.

" Hey ma." Atsumu said sleepily.

Ma and I carry Tsumu to the car. I sit in the backseat with him just in case.

~ At home~

Ma had to go back to work for a night shift, so I'm in charge of taking care of Tsumu, which I don't really have a problem with.

I cook Tsumu some Miso soup while he sleeps on the couch.

" Tsumu the soup is ready!" I yell from the kitchen

I go to the living room to check his fever. It seemed to go down a little since earlier.

"Tsumu, wake up, you need to eat something or else you'll be all skin and bones and won't be able to play volleyball when you feel better.

I guess all Tsumu heard was " won't be able to play volleyball" because he shot right up causing him to wince in pain.

" Just drink the soup to make you feel better, I know ma will kill me if I let you die over here." I said smiling.

Tsumu gladly accepts the soup and falls back asleep soon after.

~ Mama Miya comes home from work ( Now 3rd person Pov) ~

Mama Miyas comes home and calls her sons names to see if they are still awake. SHe walks into the living room to see her baby boys sleeping on the couch Osamu leaning on the side and Atsumu leaning on him.

She loves to see her boys actually getting along for once.

~ Next morning( back to Osamu's POV) ~

I open my eyes to see Tsumu leaning on my shoulder. I jolted up, causing Tsumu to wake up."

"What are you soing Stupid Tsumu!" I yell

"What do you mean you're the one who fell asleep on the couch I was sleeping on! "He shouts

"Well now my shoulder is aching." I said irritated

"Well I'm sorry I was sick yesterday!" he yells back

~ In Mama Miya's room ~

"I guess that didn't last for too long." she says sighing
