The Prologue “ forget what hurt you right in the past but never forget what it taught you till this very day, this very hour, very second.. J

ongin paced back and forth as he flashed a grin waiting for his girlfriend, outside their usual hang out which was a cafe nearby DaeSan, he couldn't help but check is phone after every two minutes to see whether she had replied. 'She'll come soon, I know it' he thought and luckily, his thought was granted. She was dressed rather casually for their three year anniversary, he furrowed his brows and shook his head at the thought, she still looked beautiful no matter what. He couldn't help but notice the gloomy expression on his girlfriend's face, her lips were curved into a small frown as she tucked her hands in her sweater's pockets. ' Maybe she's just not used to the cold ' and with that he mentally shrugged.

"Jinri-ah!" he called out to her in a gentle tone as he raised his hand to wave at her signalling for her to come closer towards him, which she eventually did, he had enveloped her into a warm hug.  As much as he enjoyed it with a fond content, his girlfriend Choi Jinri only sighed as an answer, he pulled away to lean down to give a peck on her lips but she only touched his lips lightly to block herself from him, Jongin didn't understand the situation and looked to her with a curious face as he raised a brow. 

"Jongin-ah, we have to have a talk" right there at that moment, as she spoke those words, he gulped nervously and clutched onto the box which hid his present to her, as he didn't reply, Jinri grasped onto his wrist in a soft manner and pulled him along with her inside the cafe and settled down with him at a table. She tucked some loose strands of her hair behind her ear and stared at him with those big yet beautiful eyes of hers, he could see ... sadness? but he didn't know why. 

"Jongin, do you love me?" she asked with a sincere yet calm tone and he looked at her with an 'are you kidding me, of course I do' expression. He reached out for her hand to hold onto it with a slightly tight grip as he leaned closer towards her with a doubtful facial look.

"Why are you asking me this? d-did I do something wrong?"he questioned quietly, barely a whisper, but loud enough for her to hear him, he took his other hand to his thumb against her cheek caressing it in a loving manner, she shook her head to only to take a hold of his hand to pull it away from her.

" Mianhae.. let's break up "

The depressed boy ran his fingers through his brunette locks and released a sigh, he clenched his fists in anger and hit the hard surface of his bedroom wall 'Why must it be me who feels this pain?' he didn't care whether he was bleeding or the fact that his maids past his room with worried looks upon their faces as they muttered to one another in curiosity to what happened to the one so 'happy' boy called Kim Jongin. He took a seat at his king-sized bed and felt a single tear slide down his cheek before speaking to himself vowing what he had said.

"Alright Choi Jinri. you broke my heart, then I'll make sure everyone feels the way I did, I will make you mine again one day" he vowed as he tugged his lips into a sinister smirk, unlike his old self, he was no longer Jongin but now he was the opposite, 'Kai'.

It was another school day, usually he'd be happy to see his ex but ever since that heartbreaking incident, no longer was it the excitement of love but something far more menacing. As he entered, of course the girls squealed in delight as he made his way inside, for the kingka he was, he just shot them a cold stare only to wink at them as
