Apparently, for whatever reason. Her new ability wasn't blocked by Muku's barrier.
Maybe because the barrier only blocked natural sound from passing through. Or maybe being practically the mansion's admin gave her some undiscovered privileges.
Well, whatever the reason. What mattered was that she was able to "see" everything. At first, she was shocked, then she quickly cut off the ability.
However, her disbelief abs curiosity made her look again. She had to be certain that it wasn't just her ability malfunctioning. Fortunately, yet unfortunately, at the same time, her ability was fine.
She wanted to cut it off again. However, like any stereotypical girl who found people having sex in manhwa... She just couldn't look away.
Fortunately, the images were something only she was seeing in her head. So, Iris was completely in the dark. Her face kept on getting more and more heated the more she watched.
