S. Coups, Woozi, and Mingyu would panic a little and threaten to kill you if you compromise their information, though they weren't sure they could actually follow through with that.
Hoshi and Wonwoo would indefinitely just tell you they're going to have to get rid of you, no matter how much it hurt them.
Jeonghan, Jun, and Seungkwan would somehow find a way to get back at you for betraying him without actually harming you in the process, seeing as it was hard for them to get rid of their feelings.
Joshua, The8, and Vernon would be the ones to know what to do the least, and they feared that telling anyone would cause your disappearance; they continued their relationship with you with lots of caution.
Dino and Dokyeom would probably be the most emotional about it and immediately confront you about it; they would threaten to turn you in or kill you many times but they would all be empty threats.
