Arima Kousei woke up on his bed feeling too tired. He still found himself inside his hospital room with all the machines and tubes connected on him. His tears fell down his eyes when he remembered Miyazono Kaori, his first love. He laid on his bed sideways. He held on a pillow and cried. He hated being sick and hooked up with too many machines.

Suddenly, he felt nauseous. He decided to stand up and go to the bathroom inside his room as no one was there to assist him. As he got up, he held on his IV stand and walked but his legs were shaking. He rolled his IV stand carefully but he wasn't able to reach the bathroom since his legs were aching so badly.

He decided to take the bucket on his own under his bed to vomit but at the same time, it was just in time when his father entered his room where he found him vomiting.

There was no food again that he vomited.

It was just acid.

His father quickly went closer to him. "You alright now?"

Kousei nodded. He let his father hold his shoulder. He sat on his bed and laid back down slowly on his bed after he had water. "I really think I need a psychologist, dad. I don't want to feel this way, anymore but I have to learn to accept it."

His father held him tight as he knows that he doesn't have anything to tell him. What he just need is to be comforted.

For the past four months, Kousei's life circulated on taking his chemotherapy pills, radiation therapy and most of all, sleeping for too long inside his room. He had visitors for a few days until his doctors found out that his immune system dropped down again. He was isolated for a while to keep him safe from any germs and viruses.

He had already began feeling so unusually tired and irritated for being exposed to many chemicals and radiation. He lost his hair three months after he was admitted in the hospital, too. It was also the time when Tsubaki and Watari returned in Japan already.

Kousei doesn't want her to go as she helped him a lot to cope up with his disease but because they are both athletes and scholars in Japan, he knew he had no choice but to let them go. He can't let them suffer at the same time he's suffering. He's happy that his two closest friends had met each other when they chose to visit him in the US. His four friends were able to bond with each other after they met and he's grateful for it.

His father became really troubled when his son's mind had fogged a week after his closest friends left the hospital. He doesn't know what's happening around him which worried his father so much. Kousei's awake but he became unresponsive.

He was just breathing like a living doll lying on a hospital bed.

Arima Takahiko cried out to him while he stare at his son's empty eyes. "I know you're in too much pain right now. Son, you're very important to me."

Seto Hiroko was also there, praying that his child would respond to them again. She's definitely hurt too by what's happening to Kousei. "Why can't he respond to us, Takahiko? What are all they doing? Kousei's getting worse!"

"His doctors said to me that it was a side effect of all the strong medication he's in," he told her. "Kousei's in a catatonic state right now."

Weeks later, Kousei woke up aware of his surroundings again. He began stuttering and he can't move his own legs which made him cry bitterly and afraid of the future. His arms were also very shaky. His father had to wear a mask and a white uniform to be allowed inside the isolation room. At the time his white blood cells had returned to its normal number and there's no danger that he might be easily infected by any germs outside the isolation room, his doctors checked him again and ran some tests that day. They were pretty much happy that he had already woken up.

He was discharged a week later from the hospital after five months of intensive radiation and chemotherapy since the tests began showing that he's recovering already. He began speaking straight again after a week he got out of the hospital but he still can't walk. He was able to play his piano again days later, too. While playing Love's Sorrow on his piano, it reminded him of his suffering inside the hospital.

He would still be taking a few pills every week to prevent his cancer cells from growing and spreading in the other parts of his body. He remembered how lucky he was that he had met Dr. Florence Jane. She is a beautiful woman with green eyes and blonde hair. Without her, he couldn't have survived his illness during the time the chemotherapy is too harsh on him.

Every now and then, even if he got out of the hospital, his psychologist would come and visit him. He stopped playing his piano after a while when he felt tired. He rolled his wheelchair near his bed and he tried to feel his legs. When he did feel it, he tried to stand up, held on a wall and walked slowly until he's able to reach his bed.

After a while, his father came inside his room. "How are you?"

"I still feel sick, dad," he told him. "I'm still taking pills, right?"

"Yes. It's to prevent your tumor from metastasis. We can't let your cancer metastasize," he told his son. "You still have a few cancer cells, Kousei. It will disappear if you just keep up and you don't miss drinking your pills. Your doctors sent you home so that your healthy cells could recover."

"When will I be able to go back to school?" he asked his father.

"You must know that your school dropped a lot of things for you because you are sick. They don't want to force you anymore in doing things that will stress you out," his father reminded him. "Maestro Alessandro's happy to know that you are discharged but it will take time for recovery, Kousei."

Kousei laid down on his bed and closed his eyes. He does miss Tsubaki.

The next day, he heard two people talking inside his room.

"He's still sick. He just got out of the hospital," Takahiko told his father, Dr. Arima Sui. "I still wonder why Kousei's still too fatigued."

"Radiation therapy side effects should disappear a week from now," Dr. Arima Sui said to his son. "Even so, it looks like it's not yet disappearing."

Kousei felt that someone was checking his temperature when a hand touched his wrists. He slowly opened his eyes and looked at the people in front of him. He touched his head and since he's ashamed of being bald due to the treatment he had, he quickly grabbed his beanie and wore it after seeing that his father does have a visitor which made the two adults laugh.

"It's fine, Kousei," his grandfather told him. "I can understand that you're ashamed of what you have right now but I am also a doctor like Dr. Brown. He called me and said that you are already released from the hospital. Most of all, I am your grandfather. Do you remember me?"

Kousei shook his head. "This is my first time to see you."

Takahiko looked disappointed. "He'd only seen you as a three year old. After that, I didn't know you left to study medicine here in USA and went back in Japan to practice medicine."

"I'm a neuro- oncologist. I know what you had gone through," he told Kousei. "It's actually good that you didn't suffer from other severe side effects after treatment."

"You're my grandpa?" he asked him weakly.

His father smiled. "Yes. He is your grandpa."

"Your son needs to go back in the hospital," Dr. Arima Sui told him.

"Wait, why?" he asked him.

"He's got a very high fever," he told him.

Takahiko quickly went closer to his son again. He looked at the thermometer his father used and he's definitely surprised to see that his son does have 39C. "Dad, what's wrong with my son?"

"He could be having another infection or something more. Your son needs immediate health care. Call an ambulance," he told him. "Kousei's having fever."

"I don't want to go back there," Kousei whimpered. "Nurses kept on poking me with needles."

"It might just be a simple infection, son. We'll have to go back in the hospital," Takahiko assured his son. "It's for your well being after all."

Kousei nodded and so, his father helped him walk to his wheelchair.

"I'll bring him in the hospital myself," Takahiko told his father.

"What your son needs is an ambulance," Sui reminded him.

Suddenly, they heard Kousei tell them, "I'm fine with my dad bringing me back in the hospital than an ambulance."

"Okay. I'm coming with you," Sui told them.

A few hours later, Kousei found himself back in the hospital again. He's surprised to see himself back in the hospital but he understood. Ever since he had cancer, he knows that he'll be in and out of the hospital just like a familiar violinist he adored.

Meanwhile, Takahiko's just looking at him from a transparent glass wall while Dr. Brown is at his left side.

"How are his blood tests and other tests, doctor?" he asked him. "Is he alright?"

"He still have cancer, sir. Your son's having another high fever. We'll be keeping him in here and will be kept monitored in a regular room at the VIP Ward in the Neurology Ward upstairs," he told him. "His cancer cells aren't aggressive anymore but if we stop giving him his medicines and scheduled radiation therapy, he won't last a day. Your son's cancer luckily didn't metastasize."

"Thank you, doctor," he looked back inside and asked, "Can I get inside?"

He smiled and agreed. "Just wear the right clothes."

A few seconds later, he is already inside Kousei's room. He seemed very much uncomfortable seeing his father wearing a facemask but he knew that it's a normal procedure since his nurses and doctors do the same thing.

"Where is grandpa?" asked Kousei. "I want to see him."

"Father wanted to check on your progress himself. He's also a doctor like your doctor," he told him. "How do you feel?"

"I'm doing fine, dad," he answered.

"Are you sure?" he asked him.

Kousei nodded.

After that, his eyes drooped down and he went to sleep.

"Your names are Dr. Lee and Dr. Gareth, right?" Arima Sui asked the two doctors near their offices.

Both of them looked at him. "Dr. Brown told me that he met you before in a conference."

"Yes," he smiled at them. "I'm Dr. Arima Sui."

"What do you want?" Dr. Gareth asked him.

"I'm not a doctor here but my son's son is in deep danger," he told them. "I want to know if you diagnosed Kousei correctly."

"You want to see Arima Kousei's CT Scan and MRI?" Dr. Lee asked him.

"Yes. I want to see his MRI after he was given surgery on his head," he told them. "Who operated on him?"

"Dr. Fuji Daisuke's the one that gave him surgery. He was diagnosed in Manhattan Medical Center," he explained to him.

He was given a copy of the CT Scans and MRI after that. "Thanks."

Both of them had left to find their boss and when they found him, Dr. Gareth asked if they need to do another MRI for Kousei Arima in the laboratory of the hospital.

"We will only do that after his fever has gone down a bit. We'll wait until tomorrow," he informed them.

"Understood, sir," Dr. Gareth replied. "I'll do that, then."

"Have you already given him IV antibiotics?" Dr. Brown asked him. "He needs that medication."

"We told a nurse to do it," Dr. Lee replied to him. "As we have heard, he's sleeping as of this moment."

"That's fine for now. I'm going to talk and have a chat with his grandpa as we didn't see each other for so long. I heard he learned about his grandson's condition," he said as he step out of the laboratory.
