In a humble thatched house in a poor village, male twins were born at the same hour on the same day. The parents had almost nothing, but there was one thing they wanted to cherish: their names. So, clutching their last bit of money, they walked a long distance to find a shaman. The shaman stared at the two for a long time and then gave a low laugh. "There is no need to worry. The first is destined to be a genius who realizes the principles of martial arts, and the second will be a great hero who commands the world." A look of relief finally appeared on the parents' faces. But the shaman's next words were cruel. "Call the first Seon-ye and the second Cho-yun. However... these two are a destiny of dark skies to each other. If kept together, they will consume one another, so they must be separated. Send one far away." In an instant, the inside of the house became as silent as if it had frozen. How could they force twins into a lifelong separation? In the end, the parents shook their heads. They couldn't do it. The two had been holding each other's hands since birth and didn't let go even in sleep. As time passed and they turned five, they were already extraordinary. Seon-ye read texts even though no one had taught him, and when he held a brush to paper, he wrote characters clearly. Cho-yun was different. From the moment he could walk, he moved heavy boulders with his body and helped with work that grown men struggled with, all while smiling. Seeing this, the parents' hearts sank. It was because the shaman's words came back to them. Eventually, on a rainy night, they forcibly tore apart the twins who were holding each other's hands tightly and refused to let go. That second child was me. Around the time I collapsed from exhaustion after wailing, the Sect Leader heard my cries and took me in. I grew up there. I missed my brother so much, but it was already irreversible. One day, when my tears wouldn't stop out of sorrow, the Sect Leader saw the way I held a sword and told me to choose a Master to serve. I chose the one person who stood out exceptionally among the crowd. A person with snow-white hair and an aura so pure it felt cold. I soon regretted that choice. My Master, Guest. His personality was incredibly eccentric. He had only four disciples, and the eldest, Nam Pung-yak, acted all high and mighty as the senior disciple. Furthermore, the Master seemed displeased with everything I did. So, I became stubborn. With the thought of putting Nam Pung-yak in his place, I devoted myself to swordsmanship and eventually became the head disciple. However, I lived like a profligate, causing trouble on purpose. It was because I wanted to provoke my Master. Then, one dawn, it happened when I returned from a brothel. Master was standing there as if he had been waiting for me. And that night, I was tied up and beaten soundly. Strangely, at that moment, I suddenly realized. Ah, this person... he's angry for my sake. Once that thought occurred, my heart began to beat strangely. Since that day, I became obedient to my Master. But then, this time, Master started to avoid me, slinking away whenever I approached. ...Ah, Master. You really are far too cute.
