Forum:Bounzer Guard after the fact

During one of my local tournaments, my opponent targeted my Hammer Bounzer with Riryoku, and afterward (not chaining it), I activated Bounzer Guard. The judge there said that, because of that, Riryoku stopped targeting Hammer Bounzer. I'm not sure this is true, but I'd like clarification on it; if a Bounzer monster is already being targeted by a card effect by the opponent, and I activate Bounzer Guard after it resolves, it doesn't stop being targeted by that effect, does it?
