They kinda confirmed it a few ch back when they was on the phone sihyeon with Daejun in the bathroom when he relized Daejun knew but didn’t say nun cause they don’t wanna sound crazy ig but I think they will let it out eventually… hopefully
So chapter 114 confirms that "Sihyeon" knows that Daejun realize he's actually Hajin.
I get that they're scared to outright admit it, worried that this "House of cards" can fall down negatively changing their current relationship. I would prefer if they just outright admitted it, as this roundabout way of doing it is confusing.
Also, I really wish Daejun would just say his name at least once already, when he's talking to him. So frustrating.
However I still love the story overall.
