A few more days again after he had been out of the hospital, Kousei was brought back with an ambulance since he fainted before he got on the car of his father but he's a bit conscious after he fell down. It shocked Arima Sui and Takahiko, of course. A few minutes in the Emergency Room, Takahiko found his son being brought in his room with Kousei, still unconscious. The doctors had already put him in IV Fluids.

Half an hour later, Dr. Brown faced the two closest family members. "Your son needs urgent surgery. It seemed he had a blood clot on his brain and it's about to pop. We have to get it out of his brain."

"What?" Takahiko asked him. "How did he get that?"

"We'll know after we had the surgery, sir," he told them.

Kousei had his surgery inside the Operating Room for two hours. While he's inside, the surgeons had quickly drained out the aneurysm he suddenly developed. It didn't show for months after he had his fever months ago. Dr. Brown is also inside, assisting the hospital's chief surgeon.

"Do you think his brain cancer metastasized?" Dr. Edward Ross asked him.

"It will be hard to tell them if it is," he answered him while Dr. Edward just took off all of the blood clot out of Kousei's brain using a large injection.

"It's difficult treating cancer patients," Dr. Edward told him. "Why choose oncology, anyway?"

"You're a twenty-seven-year-old golden-haired surgeon who likes to gossip while there's a patient in front of you," Dr. Brown said while he took the injection after Edward handed it to him.

"I just think treating cancer patients means I would have a more meaningful life. I grew up in a very rich family. They are mostly business men but I don't like that. I surprised them when I said I wanted to be a doctor and not to be an heir of a small company," he answered him. "They were happy with my choice."

"Small, huh?" he smiled while he is stitching Kousei's head and closing it up.

"It's just a small shoe company," he answered him.

Arima Kousei spent a day unconscious on his hospital bed and when he opened his eyes, he was confused where he is.

Takahiko already approached him at the time he regained consciousness and his awakening gave him relief that he will be able to be with his son for much longer. He didn't speak yet at that time since he was too blank. Kousei just held his father's hand and looked at his father's teary eyes. After that, his father called his doctors to come inside his room.

When they went inside, they quickly checked him and they didn't ask questions to him yet. They took some more blood tests after that.

"We'll check for the reason why he developed aneurysm on his brain, sir," Dr. Lee told him. "For now, we'll keep up in giving him anticoagulants to prevent him from having blood clots all over again."

Kousei's eyes shut down again after the medicines given to him take effect. He tried to keep himself awake but without ado, he was back asleep.

Arima Kousei slowly opened his eyes on his bed the next day.He looked around and after a few minutes, he knew that he is back in his room. His father is also sleeping on his right side. His father woke up, too. When he saw that his son is finally awake, he smiled at him.

"How are you feeling?"

"My head feels heavy and itchy."

"You just had an operation for aneurysm yesterday. You woke up hours after you had it yesterday but it seems, you were not aware of your surroundings. You just fell asleep again after your doctors checked on you."

"I'm sorry for making you worry, dad."

Tears automatically went out of his eyes, once again and so, to help his emotions calm down, his father held his hand to comfort him. His psychologist had also explained to him that due to cancer, his son is acting like not himself. His son is afraid and scared. He also knows that he might not survive cancer.

"We already finished the investigation why your son had a blood clot," Dr. Gareth told him. "We thought of it that your son might have metastasis but after a few more investigation, we luckily ruled it out. Your son is heavily dehydrated and it caused his brain to have a blood clot on his brain."

He looked at his weak son on his bed who's struggling to stay awake. He's hooked up on his IVs and heart monitor as always.

"I just need to keep giving him water, right?" Takahiko asked them.

"Yes, sir," Dr. Gareth answered him. "He needed to keep hydrating himself."

When they left, he sat at his son's right side to talk to him. "Why aren't you saying anything to me? Why didn't you say that you do feel dehydrated?"

"I just didn't feel that way, dad," Kousei told him. "I thought I'm fine."

"How many times do you drink water?" he asked him. "Be honest with me."

Kousei swallowed. "I drink water only when I'm taking my pills."

"Chemotherapy dehydrates you and so, you need to be extra careful," Takahiko reminded him. "Son, I don't want anything bad to happen to you, so, please, don't stop me if I give you water eight times a day, okay?"

"It tastes like metal to me, dad," he informed him as tears cascade down his eyes. "I hate drinking those but I have to since it keeps me alive, at least."

"Chemotherapy distracts your taste buds. I also noticed that you're not eating," Takahiko said to him as he comfort his son. "You have to eat."

"Leave me alone, please!" Kousei demanded while he's on his bed. "Leave me alone, Hiroko- san! I don't want to eat, drink or stay alive anymore! I hate waking up!"

"You need to drink your pills, Kousei." Seto Hiroko told him. "You need to eat."

"I have no appetite, Seto-san," he told him. "I'm full. I'm not hungry."

"You haven't eaten all morning, Kousei," Seto Hiroko reminded him.

Kousei stared at her and at the cooked fish fillet and rice on the table attached on his bed. If he feels healthy, he could have eaten it already but since he feels so unwell, he stopped himself.What he wants is to sleep, not eat."I'll eat it later."

"Kousei, tell me," she spoke gently. "What are you feeling right now?"

"My stomach is aching," he told her. "I can't eat."

Seto Hiroko understood. "Go to sleep. I'll tell your doctors about what you feel right now."

"Thank you, Seto-san," he told her as he drift to sleep. She covered him with his blanket and took his food back in the refrigerator for a while. After that, she reported his stomach ache to his doctors. They recommended to give him tea and some wet food for a while.

He improved after a few weeks and he was out of the hospital soon. His father and grandfather decided to go back in Japan after Kousei's health improved and the cancer cells were slowly disappearing. Arima Sui wanted him to be comfortable at home but due to his popularity in Japan, they decided to bring Dr. Florence, hired a bodyguard, and a male, personal nurse for him. He said his goodbye to Catherine and Nathaniel in the airport.

"I'll return back, don't worry," he told them. "Good bye for now."

"I hope your health improves more and you won't be bothered by your sickness again," Catherine told him. "Promise us that you'll come back."

"Pray for me," he asked them.

"We will, Kousei. Promise," Nathaniel assured him. "I'll pray for you."

The airport soon called the passengers for the 7:00 pm flight to Japan. He did fear that he might have seizures at the flight but his doctors assured him that since his health did improve a lot and the tumor left in his head was slowly disappearing, he would have little chance to get seizures. He also wished that when they return back in Japan, he would be able to rest for long as he doesn't need to think for school and other musical recitals he had before his sickness.

He entered it with his father and grandfather, followed by Dr. Florence, his personal nurse and bodyguard. Seto Hiroko and her family decided to stay behind since they have jobs in the US.

He sat at his father's left side near the airplane's window.

"Are you okay, son?" Takahiko asked him.

Kousei didn't need to use his beanie anymore as he grew his hair back after a few weeks after his doctors discharged him. "I'm fine, dad."

At the time they had reached Japan, as expected, there will be Japanese media all over the place to document his early return. They also seemed to have learned of his sickness as he heard some journalists and reporters asking him if he really suffered from brain cancer. His bodyguard, Kristoffer Grahams, quickly shielded him from them and he was truly able to do it due to his large build. His father and grandfather soon begged them to leave Kousei alone.

They confirmed the truth about the rumors that Kousei was diagnosed with brain cancer at the middle of his school year and he is forced to drop it for a while. He will return in Juilliard School after a few months. Kristoffer took Kousei in a private room in the airport with Dr. Florence and his nurse soon.

Of course, his nurse quickly asked him, "Are you okay?"

His name is Yaichi Yurinosuke. He does have brown eyes and fair skin. He realized that Kousei's so dizzy and nauseous after he examined him. He quickly took Kousei's medicines and gave it to him in which Kousei received and swallowed willingly. He closed his eyes and went to sleep. It was a big shock to him when he found himself being wheeled to go to his father's car in the parking lot when he woke up.

"What? What happened?" he asked them. "What happened to me?"

"You have nothing to worry about, okay?" Takahiko told him. "You need rest. Stay asleep for now."

The truth is, he collapsed after a few minutes inside the private room just after he opened his eyes and stood up.
