The only way i'm able to give sense to Grey Hair's thinking is by interpretating as follow :
1. DoHyeok cant get it up anymore
2. He eavesdrops on DoHyeok being a bottom and getting hit/played around by Siwoo.
3. DoHyeok is a proud person
= DoHyeok likes to be dominated as a bottom but doesnt want to aknowledge it or something.
And therefore he planned the gangrape expecting DoHyeok to be mad at first, but to eventually like it. For him it SEEMS to be like "let's have fun, it's no biggie"
That is quite a stretch but otherwise... How else to explain him still wanting to hang out with DoHyeok after what he has done?
