In the burning summer day, the sun is shining high in the sky.

Yin Xixi just entered the changing room at the swimming pool when her phone's ringtone started to sound.

"Xixi, today is your birthday. Originally, I planned to celebrate it with you. But something came up at the last minute, so I guess I'll have to celebrate your birthday with you later. Xixi, happy eighteenth birthday!"

On the other end of the phone, Yin Tianrui was speaking with a low, doting voice.

"Brother, it's okay. As long as you don't forget to give me a gift." Yin Xixi's face was full of happiness. Today was her eighteenth birthday, which meant that she, Yin 'Demon King', had been wreaking havoc on the world for eighteen years already. However, fortunately, she had an awesomely handsome brother who was incredibly good to her and always cleaned up her messes. This was what allowed her, Yin Xixi, to act with such 'domineering arrogance' for eighteen years.

"Xixi, remember to come home quickly after you finish swimming. Don't loiter around outside. Also, when I'm not at home, remember to lock the door securely. If someone rings the doorbell, ignore them. If the house phone rings, don’t pick up…"

"Brother, I'm eighteen now, you can't always treat me like a child." Upon hearing Yin Tianrui's loving admonitions, Yin Xixi was very dissatisfied. From the moment she came of age, her brother had always advised her of these things. As a child, she would obediently listen, but now she was eighteen. Her brother was still repeating these admonitions, this was clearly treating her like a baby, it was so annoying!

Yin Tianrui chuckled softly on the other end of the phone, his voice doting as he said, "No matter how old Xixi gets, in brother's eyes, you will always be a child."

Yin Xixi pouted, about to argue against his words. But Yin Tianrui, in his hoarse, seductive voice, said, "Xixi, do remember this. Your brother is the only person in this world whom you can trust and rely on. Unless the day comes when I die, no one can separate us."

"Brother, today is my birthday. Can you stop saying such sentimental things?” Yin Xixi pouts. Her brother, Yin Tianrui, is only five years older than her. Since she could remember, it was always her brother who played the roles of both her mother and father, raising her till now.

However, her brother is a very mysterious person. She does not know what his profession is, but every year, he would be bustling around abroad for a month or two. In that period of time, even if she called him, his phone would be off, unresponsive.

She had asked him many times about his job, but her brother never told her.

"Alright, let's not talk about this anymore. Xixi, have fun. Your brother has to get to work. See you in the evening!" A hasty sound of footsteps came from the other end of the phone, Yin Tianrui's voice suddenly became stern, then the call was quickly ended.

"See you tonight!"

Yin Xixi also hung up the phone, placed her phone into the locker of the changing room, then picked up her swimming suit, ready to change clothes. But just as she was about to take off her bra after removing her coat, the changing room door was suddenly smashed open by a strong force.

Yin Xixi jumped in fright. Before she could react, her mouth had been covered, and a black handgun was pressing against her head.

"Don't scream!" A cold, male voice whispered in Yin Xixi's ear.

Yin Xixi's body tensed up, and a faint smell of men's cologne assaulted her senses.

Although Yin Xixi was jokingly referred to as "Yin the Tyrant" by others, this was the first time she had been threatened with a gun. Her legs trembled involuntarily, and it seemed as though her heart was about to leap out of her chest.

"If you want to survive, just do as I say!" The man's commanding voice echoed in her ear.

Yin Xixi nodded obediently. Clearly, the man with the gun was the boss. For the sake of her own life, she had to obey.

Shortly afterwards, the sound of hurried footsteps echoed outside the dressing room, seeming to indicate quite a number of people.

"You all better search quickly. If we can't catch him today, we won't have the face to go back and report to the boss," an angry roar from outside made Yin Xixi shudder again.

It appeared she had the misfortune of encountering a gang feud.

Yin Xixi's face twisted miserably. Today was her 18th birthday; the heavens were really treating her well, giving her such a "surprising" present. Now, she was genuinely "surprised," yet there was little happiness to be found.

While she was still in a state of confusion, she suddenly felt an additional hand on her waist and remembered the man who had seized her. Looking up, she met a pair of icy blue eyes.

This man is really handsome!

That was the first impression that crossed Yin Xixi's mind upon seeing the man before her.

His tall, sturdy figure, his chiseled striking features, sparkling blue eyes, and his tightly pursed thin lips - all these elements combined on his face, giving him a harmonious and charming appearance. Coupled with the regal aura he exuded from head to toe, this man could be summed up as simply top-notch.

Yan Siyao raised an eyebrow as he glanced at the girl before him. She was pretty and delicate, not the type he disliked. With a swift pull, he tore off her top.

"Ugh...." Feeling a sudden chill, Yin Xixi immediately pulled her thoughts away from daydreaming, and made a "ugh" sound in her mouth.

Yan Siyao’s face, which seemed to be chiseled by a knife, looked deeply melancholy like Satan at the moment.

He didn't heed Yin Xixi's refusal, he pushed her against the wall and stooped down to kiss her.

On Yan Siyao's frosty, handsome face, his brows were coldly furrowed, and that frightening aura headed straight for Yin Xixi. Then, Yin Xixi felt the world spin before her eyes, and before she knew it, she was on top of this man. Because of this, she "accidentally" saw the man's impressive upper body.

A narrow waist and firm hips, not an ounce of extra fat, and eight enchanting abs entranced her gaze.

She swallowed hard, wishing she could reach out and feel it if not for the dangerous man in front of her.

"Bang!"

Another sudden loud noise brought Yin Xixi back to the present, and she listened attentively to the sounds outside the bathroom stall.

"The boss of the Yunlong Club actually has to hide in the women's restroom. Yan Siyao, don't you think this is pathetic?" A menacing roar erupted. The next moment, another deafening noise, and the door of their hiding place was kicked open.

"Ah!" Realizing she was naked, Yin Xixi screamed.

"What are you doing?" Yin Xixi instinctively pressed her bare upper body against Yan Siyao. Yan Siyao put his head on her chest and embaced her, pressing his head even harder against her.

The person in charge of chasing Yan Siyao was named Reno. Reno hadn't expected to see such a scene when he kicked the door open. He was taken aback for a moment, but his eyes narrowed slightly when he saw the man's physique.

"Yan Siyao, I didn't expect you to stoop so low as to hide behind a woman," Reno remarked mockingly.

Yin Xixi felt wronged by being looked at this way, and the man in front of her was gripping her waist so hard. If she didn't do something soon, her waist might be crushed by his grip.

She turned her head to look at Reno, seeing that he was a foreigner with white hair and blue eyes. She took a moment to gather her thoughts, and then mustered up the strength to curse, "Yan Siyao? He's my man, we're just doing things in the bathroom. What's it to you...and you, staring at us like that, aren't you afraid of getting a stye?"
