I own nothing
Isshin let out a yawn and stretched his arms before leaving the bathroom to check on his children.
Ever since his wife passed away, Isshin made it a habit to check on his children before going to bed himself. It made him feel better to see his son and daughters safe and sound in bed.
He went to Yuzu's room first. He gently and quietly opened up her bedroom door and looked inside. Isshin found her curled in a ball, fast asleep. He smiled before closing her door and going to Karin's room. He found her sprawled across her bed, fast asleep as well and snoring fairly loudly but her blanket was on the floor. He went over and picked up Karin's blanket before covering her back up. Then, Isshin walked down the hall towards his son's room. He was going to open the door when he heard coughing.
'Ichigo!' he thought with worry.
Isshin opened the door and found Ichigo sitting up in bed, having a coughing fit. He went over and sat down next his oldest child before rubbing his back. Once the coughing fit stopped, Isshin pressed the back of his hand to Ichigo's forehead.
"Dad?" the orange haired teen asked, his voice rough from coughing.
"You're burning up," the older man told him gently, removing his hand. "Wait here while I get some supplies."
Then, he stood up and began to make his way towards Ichigo's door.
"D-Dad," Ichigo hoarsely called, reaching for him, intending to stop him.
The older Kurosaki stopped and turned towards his son.
"Just wait there," Isshin ordered in a gentle but firm tone. "I'll be back."
The teenager sighed but nodded and didn't try to stop him. Isshin turned back around and continued on. He went towards his room and grabbed the doctor's bag he keeps in his room for his family. With that in hand, Isshin made his way towards the bathroom and grabbed the medicine. Once he had the items he needed, the black haired man went back to Ichigo's room. He found the teenager trying to cough quietly. Isshin walked towards Ichigo's bed and sat down on it next to his son.
"I'm going to check your vitals, Ichigo," his father told him, going into Doctor Mode and placing the bag on the floor in front of him before opening it up and taking out some supplies. "I need you to be still."
Ichigo looked up at him before letting out a huff and giving his father a tired glare.
"It's just a cough, Dad," came the hoarse response.
Isshin pulled out a thermometer and cleaned and dried it first before offering it to his son.
"And a fever," the older man continued.
Ichigo frowned at the thermometer but took it and turned it on before placing it under his tongue. Then, Isshin took Ichigo's left wrist and began to take his pulse. He stayed quiet while he took his son's pulse and, unknown to his son, his respiration rate. After a while, the thermometer began to beep. Isshin let go of Ichigo's wrist and took the thermometer out of the teenager's mouth.
'38.5⁰ C'
'That's quite a fever he has,' the older man thought with concern as he placed the thermometer on Ichigo's bedside table.
"You're running a fever of 38.5," Isshin told him before picking up the blood pressure cuff and stethoscope he took out earlier. "Now, lift up your sleeve."
Ichigo let out a couple of coughs while he lifted up his left sleeve and offered his arm to his father, looking irritated. Isshin wrapped the cuff around Ichigo's upper arm and then placed the diaphragm of the stethoscope in the crook of his elbow.
"Now, you need to stay still or else the reading won't be accurate," Isshin ordered.
Ichigo rolled his eyes.
'I know,' he thought.
Then, his father inflated the cuff and then waited for a moment before deflating it. When he was done, he unwrapped it and took off the stethoscope.
"Your blood pressure has risen," Isshin told him, putting the blood pressure cuff back into the bag. "So has your pulse and respiration rate."
Ichigo looked confused.
'Respiration rate?' the teenager thought.
"My what?" he asked before letting off a couple of coughs.
"Your breathing," his father clarified. "Since your heart is working a little harder to get blood through your body to fight off the infection, your cells need more oxygen so you breathe faster."
His son gave him a sour look.
"Great," Ichigo responded in a sarcastic tone. "Just what I need."
Isshin ignored the response.
"Now, besides the cough," Isshin went on, "is there anything else bothering you?"
Ichigo went quiet for a moment, thinking. Then, he shook his head. Isshin sighed at this, knowing that Ichigo wasn't being truthful.
"You sure?" he asked. "No headache or sore throat? Nausea?"
Ichigo was going to shake his head again but stopped and began to rub his throat.
"Well, it does kinda hurt to swallow," the teenager admitted.
The older man nodded. Then, he reached into his bag and took out a pen light and a tongue depressor from a small container. He turned on the pen light.
"Ahh," Isshin prompted.
Ichigo sighed a little.
"This is so stupid," he muttered before opening his mouth wide. "Ahh."
Isshin peered inside Ichigo's mouth before letting out a 'hmm' sound.
"Your throat is red but it doesn't look like strep," he said, turning off the light and putting it away. "Is anything else bugging you?"
"No," said Ichigo, shaking his head. "Honest."
Then, he began to cough roughly. Isshin rubbed his back until the coughing fit passed. Once it did, he put the stethoscope back on.
"I'm going to listen to your lungs then you're going to take your medicine and get some rest," said Isshin.
Ichigo looked over at the medicine and saw it was the liquid kind. He made a 'yuck' face.
"I'll get you some water before you take it," Isshin told him.
The fifteen-year-old nodded.
"Ok," came the hoarse reply.
Isshin then pressed the diaphragm of the stethoscope onto Ichigo's chest.
"Now, I want you to breathe through your mouth," he said. "And be still. I won't be able to hear properly if your shirt is moving."
Ichigo nodded again. He relaxed and kept still while his father listened to his lungs. Once he was done, Isshin took off the stethoscope.
"Well, your lungs sound fine," he said, putting the stethoscope away. "So, you don't have a chest infection."
"Then what do I have?" Ichigo asked in an irritable tone before coughing.
The older Kurosaki rubbed his son's back until he stopped coughing. Once the coughing stopped, he reached over and opened up the medicine bottle.
"It sounds like the flu," he told him, pouring out the correct dose for Ichigo into the cup. "A week of rest will do you good."
Ichigo's eyes widened.
"A week?" he asked. "I can't stay in bed for a week. I'll go crazy."
"I'm sorry son," said Isshin, handing the cup to him. "But if you don't rest, then you'll get worse and have to rest even longer."
Then, he got up to get him some water. Ichigo glared at the cup of medicine.
"This sucks," he muttered before throwing the medicine back. "Cherry flavor. Yuck."
Isshin was quickly back with a bottle of water. He handed it to Ichigo, who quickly downed half of it.
"Thank you," breathed the fifteen-year-old.
Isshin gave Ichigo a small smile and smoothed back some of his hair.
"Now, get some rest," he told him. "Call me if you need anything. I'll be in my room and the door will be open. Ok?"
In reality, Isshin didn't feel comfortable with leaving his sick child alone at night even though he was fifteen. He wanted to stay with him and make sure he was alright.
Ichigo nodded tiredly and let out a few coughs.
"Ok," he answered hoarsely.
The teenager placed his water bottle on his bed side table and laid down in his bed while his father covered him with his blanket. Isshin placed a kiss on top of Ichigo's head and smoothed back some more of his hair before picking up his bag and making his way towards the teen's door. As Isshin walked towards his room, he heard Ichigo cough some more. He quickly went back to Ichigo's room and peeked inside. The orange haired boy was still laying down but he was facing his window. Ichigo coughed some more so Isshin went back over and rubbed his back to help stop the coughing.
"Dad," Ichigo spoke after the fit subsided and turned towards him. "I'll be fine. Go to bed. If I need anything, I'll let you know."
Isshin frowned at him, concern drenching him.
"Are you sure?" he asked in a worried tone. "You sure you'll be alright?"
Ichigo sighed before let off a couple more coughs.
"Yes, Dad," he told him tiredly, turning away from him. "I'm sure."
Isshin was still concerned about him but he, as much as he didn't want to, left, closing his bedroom door behind him, and made his way to his room. He placed the bag on the floor near his bed so he can just grab it in case his son needed him during the night. Then, he quickly changed into his pajamas. He then decides to check on Ichigo one last time before he went to bed. Isshin tip toed to back towards Ichigo's room. He opened the door and peeked in one last time. He saw a sleeping Ichigo, his face tinged red from his fever, now facing his closet and quietly coughing a bit.
"Good night Ichigo," Isshin whispered.
Then, he closed Ichigo's bedroom door and went back to his own. He left his door open a crack just in case Ichigo or one of the girls needed him. Worry coursed through his veins as he laid down to go to sleep.
'I hope he'll be ok,' Isshin thought to himself before closing his eyes and falling into a worried sleep.
