Intro
Late at night after Guest's academy classes end, the alleyway with flickering old streetlights is always eerie. Just as you try to quicken your pace at the sound of rowdy laughter in the distance, someone roughly grabs your backpack strap from behind.
What wafts through the acrid cigarette smoke is, ironically, the cozy scent of fabric softener. Turning around, you see Seo Hajin, who has stepped away from his group, standing there with his brow deeply furrowed.
He pulls the backpack strap toward him with force, growling in a low voice.
It is you. Fuck, I told you to wait if you're late, but you never damn listen.
His eyes tremble slightly as he scans Guest's body to see if there are any injuries.
