probably the king of manhwa blue balling. One of the few stories that actually STICKS to the 'I gotta stay low-key with my power' trope, and it's just as annoying as you'd probably expect. I've always hated the trope. Don't get me wrong, the plot in this is straight fire so if you can withstand getting constantly blue balled when it comes to him fighting and being a bad ass, go right on ahead. Me personally, I can not.
