At a certain mansion

A butler was running to the head of the household. "Master, I have a bad news. Your grandson, Kamui-sama has disappeared. His room was empty and we couldn't track him everywhere. It seems that he's going to the outside world. First, Takumi-sama and now Kamui-sama. What should we do?" he panted.

"Let him be. He may have not recovered fully, but he is my grandson. He's strong. He can make it on his own"

"But, we've just revived him. He could hurt himself and he could barely walk" the butler worried.

"Don't underestimate my grandsons. They're strong and independent. Just let him be and see what happens" he grinned.

Even though her mother was taken the hospital and despite of her condition, she could control herself. She accepted it and act calm. Meanwhile a girl was walking to the front door and stopped by Misaki.

"Yuki, are you sure about this? Don't leave me with that outer-space alien!" she begged Yuki to stay. "I'm sorry, Misaki. You know Yukimura can't do the paperwork that much. He asked me to help him. You have to trust Usui to protect you, and besides…" she stopped for nearly 2 seconds, and moe moe flowers came out from her. "I want to know what he will do to you when both of you are alone together. Although I really want to know the detail, it's none of my business. So, just enjoy your time, okay? Bye!" she waved and closed the door slowly. Her moe moe flowers were gone and she said "letting her turning into a vampire, is that even right? But I want her to live. So, I have to do it. I have to suppress her dark side with my power…" she hesitated for a bit. "Or maybe... my life".

"What's wrong, pres?" the tall blonde boy asked her that was standing in the hall looking at the door.

"I-It's nothing. By the way, why are you woke up so early? I would be happier if you stay on your bed, forever" she glared.

"I will, if you're there on my bed" he teased her. But instead of hitting him or yelling at him, she only blushed. Her expression and her face were just too cute for him. Seeing that face of hers, he walked to her making her back away and hit to the wall and placed his forehead to the wall and next to her face, which is on her right side.

"You're so sly, Ayuzawa. Stop making that cute face. I will lose control again if you keep up showing that face" he blushed.

"W-what are you..." her sentence was been cut off by Usui patting her head.

"Come on, pres. Let's eat some breakfast" he walk away from her leaving her. She slowly placed her palm to her forehead and spoke "tch! Usui you idiot".

While walking to the school, Yuki realized that someone was watching her, but she kept walking. All of the sudden, she turned her head with a lightning speed, but no one was there. That made her even more suspicious. Suddenly, some girls were squealing from behind her

"Hey! Look at that cute guy!" one of them screamed.

Seeing this kind of event, she sighed. "So, my stalker is some kind of good-looking guy, huh. Sometime, ridiculous things always happens at time like this" she smiled for a bit. But, her smile disappeared when she saw him passing her while looking at her. Their eyes met each other. The guy was running away from the girls, but he didn't expect her to see him, especially his eyes. Both of them were melted into each others eyes. And he was wearing a black suit. She keep looking at him running until he's disappeared. And she keep asking to herself "Why he seems to be familiar? Those eyes..." while a slight blush appeared on her cheeks. It's almost like she fell into his eyes. She was taken aback.

She immediately snapped out and shook her head. "Wait! Why am I like this? If this is the second wave, then I can't let my guard down". Then she sighed and said "i just hope that they're okay. I can't do anything for them right now. Please, be safe" she worried about the two people that she left to protect.

...

"What's the matter, Usui? You seems to be spacing out. Are you okay?" Misaki asked.

"No, I'm fine" he continued washing the dishes and Misaki headed to her room. "Yuki, you don't have to be the knight in shining armor. You're the person that needs to be protected. Girls shouldn't protect guys. Just for now, I'll protect Ayuzawa and you. I'll protect you until he came" he muttered.

...

It's not weird that she's so popular in school. While she was walking at the school yard, some guys approached her and tried to flirt with her, but before they could touch her, a gust of wind blew at her that made her closed her eyes. When she opened her eyes, the boys were on the ground being knocked out by someone or something. When she was in a state of a confusion, a figure was seen watching her. Of course, she immediately knew that it was the same person that "stalked" her. She ignored him instead, since she didn't really care about it. When she continued her walk, she was smiling with a slight blush in her face and she chuckled. But at that time, no one knew that it was her last smile and her smile would disappear. And perhaps, he will enter their life and changed their fate.

The awakening day, the day where humans and vampires life were at stake. Time keep running and almost reaches its destination to her fate. Is it going to be chaos or peace? No one can change her destiny and who she was. Usui dropped himself on the couch since he's already cleaned up the house while Misaki on her room who knows what she's doing, maybe studying, maybe not. He was in a lying position while he closed his face with his palm. Thinking about the vampire girl he loves. He made his resolve long time ago, that he will stay by Misaki's side no matter what. Just as he wanted to close his eyes, a sound of bang came from her room. He rushed to her room. While at it, he sensed something that really surprised him.

During his way to her room, he sensed something negative coming from her room. It was a horrible and terrifying feeling. It made his sweat drops, but his love for her can conquer everything. At the same time when he opened the door, a lamp was thrown to his direction, but he caught the lamp quickly. Slowly from hiding her face to show her face, she was no longer in her amber or red eyes, as usual everytime her vampire side began to show up. She was in a stage where her awakening day is only few days left, yellow colored eyes, the last stage.

"Usui… what are you doing here? Get out from here!" she yelled as she tried to save his life from her. She leaned to the wall and dropped her body making her sat on the floor while still leaning to the wall. And so, Usui approached her and squatted.

"Kaichou, do you really think I will leave you alone? Moreover, at this condition?" He spoke to her ear.

Looking at her yellow stabbing eyes that lust of blood, he unbuttoned his shirt and disposed his neck.

"Do it" so as he said

"I… I will never bite anyone. Stay out from this, Usui…!" she breath heavily

It became worst when she saw his neck. Her heart was thumping so hard, as if her heart was going to explode, but she really felt the explosion. Her fangs were seen, but she tried so hard to control it. Knowing that she's a hot-headed and a stubborn girl, Usui changed his tactic. Luckily for him, he found a cutter near him. So, he sliced his wrist and his blood was dripping to the floor. The dripping blood made it even harder to control her vampire side. She thought that he will force her to drink through his wrist, but that's undeniably wrong. Instead, he sucked his blood through his wrist.

Right now, his mouth was full of blood. Since Misaki wasn't capable of moving her body, he use this opportunity to force her by drinking his blood mouth-to-mouth. Not knowing his intention while she's in agony and too busy holding her pain, she didn't realize that Usui's face was really close to hers in a position where he was squatting and Misaki was sitting on the floor while he lifted her cheek again. And finally, their lips crashed.

Usui forced her to swallow his blood, but she was too stubborn to do it. He didn't give up and keep opening her mouth with his mouth to drink his blood and pushed the back of her head with his other hand. Slowly, she began to give up and swallowed it. But, she swallowed it too rush. At last for many years, she was able to drink blood again. She remembered now how pleasant and tasty a blood was. She could barely stand let alone moving, so she collapsed and Usui caught her.

"You already do your best, Misaki. I'm proud of you to be able to hold your lust and didn't want to bite anyone. Your determination was truly admirable. As expected from you, Kaichou" he smiled.

"Misaki, your pain is my pain. Your happiness is my happiness. We're in this together. I can't afford to lose you" he hugged her and continued his words while letting Misaki go from his hug. His smile disappeared from his face.

"We may have a conflict in the future, but it doesn't change the fact that I'll never leave you. Humans and vampires are living things. We have a heart and feelings. Together, we create a bond between us and share our feelings. This is what it means to be a human and vampire. It's true that some vampires are heartless and cruel, but not all of them are like that" he stopped for a while.

"Yuki. She carried a huge burden in her shoulder, but she carrying it too long and never complain about it, even though she knew that it'll lead to her death. She was nothing like a heartless and cruel vampire or an arrogant and selfish human. She was… different. She always hurt herself for the sake of others. She was reckless, just like you. She never thought of her happiness. I knew her day would come no matter how hard I tried to prevent it. Knowing that, I still want to protect her. But now, I made my decision. Even though it's hard for me, I have to let her go. You're far more important to me" and so, he kissed her forehead. "I hope it's the right decision".

Like he promised, he stayed by her side from morning till evening watching his little maid. The blonde and charming "prince" was waiting his princess to woke up. Just stayed at her side even though he didn't do anything was more than enough for him. As long as he could see her and be with her, he's more than happy. All of the sudden, the door opened and someone came in.

"She's sleeping? That's rare" Yuki wondered while looking at Misaki, but the smell of blood startled her.

"She drank your blood? You know that made the countdown goes faster, don't you?"

"I do know, Yuki. But I can't let her suffer like this"

His statement made her sighed and said "I guess it's okay, if you did it for her. I know you always do the right thing for her, Usui" she smiled at him, but it disappeared when she muttered "tomorrow, huh"

"What's that?" Usui asked

"Oh, that's right! Hey, Usui. I have a favor to ask of you and Misaki" she asked him.

"What is it?"

"I'll tell you tomorrow. i have to go outside" she left them alone.

She goes outside and closed the door. She knew that her "stalker" was hiding between these houses, but she didn't bother to look for him. Instead, she asked something to him while she leaned to the door.

"What business do you have with me?" she asked the guy that stalked her, but he didn't answer.

"Are you one of Shitzu-san underlings? Or perhaps, assassin?" she glared, but the guy still didn't answer her question.

"Hiding your identity, right? Well, I don't care if you want to hide your voice too, but if she really sent you, I will kill you with no hesitation" she declared, and then she went inside. The man chuckled and finally, he spoke.

"You think that I'm her assassin? That's very cute of you, Yuki. From now on, I'll be watching you. So, be prepared, my cute little princess" he said while looking at a picture of their past. A picture of Usui, Misaki, Yuki, and him. A picture of their childhood and their joyful moment.
