@lagers00 I don't think he could have resisted the temptation then to not take back the curse as xer0sama states. It'd be too much for him. And even if he did, then now he'd be dying from the fact that he knows what it's like and would only want it more and miss it because he's had a taste of what it's like.
Adding it to the face that Duke might be really frustrated about not touching Alice and there's also the fact that Alice just keeps teasing him...
Well, you know how he would want to pent that up.
I'm disappointed that he reverted the curse without at least kissing Alice first. Also, I'm pretty sure Rob would have been perfectly happy with his new "powers," though imouto would be pissed.
