A decade ago, 12 years old Chinese lad, Yixing met same aged Korean boy Junmyeon, it was in an Academy located in Seoul, South Korea when their paths had crossed. Junmyeon was the nerd back then, always bullied and teased, yet Yixing just stood there, watching everything unfold in front of his very eyes for he was amused. He liked Junmyeon, the first time he had laid his eyes upon the angelic beauty. Yet he ignored those cries of help. Then, everything came crashing down when Junmyeon finally had enough of the beating and left school. He got tired and sick of every bruise he would hide, every tears he would keep for himself and lastly, to put back all the broken pieces of his shattered heart. That day as well, Yixing realized his worst mistake, his first love had left. He was left with nothing as well, he had let his stupidity and selfishness took the best of him and that earned him the biggest slap at his face. He then returned to China.

Now, 22 year old Yixing, who grew up finely, with his long limbs, piercing eyes and deep dimple, known as a business elite and the hidden mafia lord, found his way back to Korea for a vacation when he met a very familiar face. A very familiar, angelic face. Who does not seem to have any recollections of him at all. . . 

What would be the outcome for these two, searching souls?
