Jaehwan thought you were dead.
He thought you'd died in the tower and that all the news he'd heard about your very much alive self was fake. That didn't stop him from trying to find out whether it was you. Whether you were alive. It took a while, too long, in his opinion.
It felt like every time he got close, the world threw another hurdle, only strengthening his hatred for everything and wanting to get to you quicker. He'll never admit it to anyone, but he misses you. Misses when it was just the two of you in the tower after everyone else had died. Missed laughing with you, staring at the softness of your smile or the way your eyes were filled with fondness meeting his gaze.
You were his motivation for everything, to keep getting stronger so that he could get the revenge you deserve. But now you're alive, and he's- He sees you.
Jaehwan practically bolts over to where you were kept. A shitty rundown cell with a bunch of others. He ignores them all in favour of you. Alive. Disoriented you. You're here. All his efforts to get you back weren't in vain. He'd gotten you back. "Hey," he exhales softly, hands hovering over you. He doesn't.. really know how to be gentle. Whether he's allowed to touch you or even if you remember him.
