The strongest hero of humanity, Kim Sung Bin.

The end of the world is coming, the world has undergone great changes, and everything has changed. Plants, animals, and even insects, as long as there are living things, have mutated.

«Grey, elemental affinity, zero» The Elder announced the result loudly.

He hated everything I was, but I searched for affection in every cruel glance he gave me.“There were so many things I wanted to say to you, but even writing them feels impossible. Because I know that if I were to put down the words I keep in my heart, you'd only say it's natural, after all, I’m just a stupid, self-centered person, like you often said.But I'm not. And that’s why I won’t bare my heart to someone who never truly knew me. Because... you wouldn’t trust the sincerity of a stranger. Right?But I did.You were the stranger whose sincerity I believed in.So I’m stepping away from being the person who embodies everything you hate—because I hate those things too.Maybe in another life, I’ll get to tell you who I really am.”
