So here is the first chapter of the long Code Blue fanfic I told you I would write. There is also a sequel fanfiction to my first One-shot but, those won't be in the same continuity as this story and its possible sequels, those will have their own continuity. Please give this one love and tell me what you think about it so I can improve.

CODE BLUE 4

When Kōsaku Aizawa opened the door of the apartment he had rented to live in during his stay in Toronto, he was surprised when he saw who was standing outside. Megumi Shiraishi wasn't supposed to be there, she was supposed to be in Japan. When she had last spoken to him, she had not mentioned anything about going to Canada for a visit.

"Shiraishi" he said, his confusion clear on the tone of his voice. "What are you doing here?" He asked.

"I'm not quite sure" she replied, her voice sounding a little bit nervous. "It just happened." Kōsaku looked at her for a few seconds without saying anything. "Does my visit bother you? Sorry, I should have called." She said, breaking the silence while looking embarrassed.

"No, you don't bother me at all." Kōsaku reassured her "But you are right. You should have called, I've just returned from working the night shift at the hospital. Come in" he added, opening his apartment's door wide and moving towards the kitchen.

"Thanks" she said, following him and closing the door. "So, how are things going in the hospital?"

"Not bad. Like I told you last week, everything is going well. I'm a bit sad that I've only three months left." He said, pouring himself a cup of coffee and offering her another one, which she accepted gratefully. "But I'm also looking forward to working at Shohoku again."

"I see…" Megumi said. "Wait… You are coming back! Didn't one of the doctors here offer you the chance to go to New York with him? To work at a pretty good hospital there?"

"He did, but after giving it some thought I decided against it." He replied.

"Huh? When!?" Megumi asked, her tone of voice a little higher than usual due to her being surprised at this new info.

"A couple of days ago" Kōsaku replied in his usual calm voice.

"But, didn't you say you had decided to accept it?" She asked, her expression telling him she was trying to put some of her thoughts together.

"I did?" Now he was the one surprised. "I don't think I told you anything like that when we last spoke."

"Yeah, you told you'd think about it but when you talked with Fujikawa you told him you were going to accept." Megumi said, explaining who she'd gotten the info from.

"I haven't spoken with Fujikawa since last month. I didn't even tell him about the offer" He said.

"You haven't?" She said, her eyes widening as she had all the info she needed to finally connect the dots.

"Wait." Kōsaku said, connecting the dots as well. "Did you come here because you thought I wouldn't be returning to Japan?" He asked, feeling happy at the thought.

"No" she said, chuckling nervously and growing redder by the second. She was obviously lying.

"So, why did you come here?" He asked. "And please, don't say that it just happened. No one goes out for a walk and accidentally takes a plane."

"Well, you've been telling me how beautiful Toronto is. So I decided to come." She gave out another weak excuse. "I didn't tell you anything because I wanted to surprise you."

"I see" Kōsaku said but, before he could say anything else, his smartphone began ringing and, after checking the caller's ID, he answered it. "What?" He said, not bothering to be polite to the caller who'd interrupted his conversation with Megumi. "Yes Aragaki, I haven't forgotten. You told me a hundred times yesterday and I recall perfectly telling you I would go." The caller replied something and Aizawa nodded. "Yeah, 1 pm. Got it." He confirmed. He then looked at Megumi, who was looking at him with a questioning expression. "By the way, do you mind if I invite someone to join us?" He asked and, when the caller asked who he was inviting, he replied. "A friend from Japan" the caller replied positively and Kōsaku showed Megumi one of his rare smiles. "Thanks, we'll see you there." He said before ending the call.

"Who was that?" Megumi asked curiously after he put the smartphone in his back pocket.

"Keisuke Aragaki. A friend from the hospital" he replied. "I think I've talked to you about him a couple of times over the phone."

Megumi nodded. The surname had sounded familiar, and she recalled now that Kōsaku had indeed mentioned him a few times. He was a Japanese doctor, a cardiac surgeon who lived together with his children. "And what exactly have you forced me to invite him to?" She asked him.

"His daughter's first birthday." Kōsaku replied.

"Aizawa! I can't go to something like that! You go, we can meet another day." Megumi said.

"Don't worry, he was thrilled when I asked him if I could bring someone with me. It was going to be him, his two children and me." Kōsaku defended his decision. "Besides, I already told him that we'll both be there."

Megumi was speechless. She hadn't expected him to include her in his plans for the day. She had come to see him out of the blue, so she had been expecting him to be a little mad. However, she knew that this gave her the chance to escape his interrogation for a while. He hadn't bought her excuses she had given him so far to explain why she was there. So she finally nodded. "Ok, I'll go but I did want to do some sightseeing today."

"No problem, I'll show you around a bit before we go. I will need to take a shower first though."

"No, I'm sure you've had almost no sleep tonight. You better take a nap before you go to lunch. I'll take a walk and check out some interesting spots. I'll meet you at lunch" Megumi said.

Kōsaku looked at her. She had a point. The night shift had been rough and he had slept very little. He would be too tired to show her around properly and also to go to lunch or to remain awake through it. Keisuke would certainly forgive him but he would never let him forget it.

"Alright. It's 8 am. Call me around 12:00 and I'll text you Keisuke's address." He said. Megumi nodded with a small smile before finishing her coffee.

At 12:30 Kōsaku appeared at the door of his friend's apartment. Keisuke opened the door and, although he was a bit surprised, he didn't mind his early arrival. "You are here a little early." He said as he shook his friend's hand and gave him a one armed hug which Kōsaku didn't return, after all, he didn't greet people as effusively as his friend normally did. "I was getting the kids ready. Do you mind giving me a hand?"

Kōsaku shook his head and, after handing his friend the doll he had bought for his daughter, he followed him towards the children's bedroom. It didn't take too long for an overly excited 3 year old to crash into him, hugging one of his legs after doing so.

"Uncle Kōsaku!" the young boy greeted him.

"Hey there Satoshi. I see you've dressed up nicely for your little sister's birthday." He said with a warm smile. "We should do something about that hair."

"Yes please!" Sounded Keisuke's voice from the children's room. "Help him to comb his hair while I finish dressing the birthday girl!"

"Alright!" Kōsaku replied, leading the little boy towards the bathroom. There he faced a mission more difficult than a lot of surgeries he had performed: trying to fix a child's hair and have him stay still for a few seconds so he could do so properly. When they both got out of the bathroom, Kōsaku was a little more wet than when they'd entered but the mission was accomplished. Meanwhile Keisuke with the birthday girl, Sakura, in his arms waited for them in the living room.

"There's the birthday girl!" Kōsaku said, smiling fondly at the girl who laughed happily and clapped a few times when she saw her uncle, prompting her father to hand her over to him. "Happy birthday little Sakura" Kōsaku said, kissing her cheek and tickling her belly, prompting more laughter. Just then, the doorbell sounded and Kōsaku gave the baby back to her father.

"That must be Shiraishi" Keisuke said, throwing his friend a knowing smile.

"How did you…" Kōsaku began to ask.

"Know who you've invited to my daughter's birthday party?" Keisuke finished the question with a knowing smile before his friend could. "Well, out of all the friends you've told me about, you would do this kind of thing only for her." He explained before he went to open the door. Once he did, both men found a rather nervous Megumi standing there with a rather big present for Sakura.

"Hello, my name is Megumi Shiraishi" The woman introduced herself. "I'm a friend of Aizawa."

"Hello, Doctor Shiraishi. I'm Keisuke Aragaki, also a friend of Aizawa. It's very nice to meet you." he said, shaking her hand and then taking the present with his free arm. Megumi smiled at baby Sakura, who seemed to like the new arrival and smiled back at her sweetly.

"And this must be the birthday girl!" she said cooing at the little girl who laughed.

"Yes, this is baby Sakura" Keisuke replied, smiling as he saw the interaction. "We are very glad you could make it. Please, come in." He added, letting her into the apartment.

When Megumi entered she smiled at Kōsaku. "Did you sleep well?"

"It was a good nap" he replied with a soft expression.

"Are you my uncle's only friend?" sounded the voice of Satoshi, who was eyeing Megumi curiously. After hearing the young child's question, Megumi blushed hard, Kōsaku would have done the same if he'd been someone who blushed easily and Keisuke just laughed.
