Zenith. The superhero that everyone in Seoul knows and loves. His superpowers make him nearly unstoppable: strength, speed, vulnerability, and flight all make him the type of hero that people once thought were only possible in comic books. But that's what happens when someone is the son of two superheroes, it seems.

But there's a whole other side to Zenith, one that not too many are aware of; Lee Jeno. A young lawyer who fights for fair judgment and justice for those without a voice. In some way, he saves people in both fields of work, though it's not like very many people know about that.

Some nights, the quiet ones when no crime seems to happen, Jeno finds himself pondering what his life could look like if he were born differently. If he was born and raised under different circumstances; maybe he'd be married, or working as just a lawyer instead of technically working two jobs, maybe he would have more time to travel or make new friends... would he be happier in that world?

So many 'what if's fly through Jeno's mind in the quiet nights like this. All of them go unanswered, though. Because they're not real. What's real is the city in front of him right now, the streets full of people that are counting on him to be there in their time of need.

It's a big responsibility, being the one that people count on so heavily, but Jeno doesn't let the idea of responsibility hold him back. He's Zenith—the Zenith. If he can't save them... who can?
