I thought that too a first me then I started thinking maybe he WANTS to say something like that, something negative or bad about Tofu Face but he didn't actually dig up any dirt (coz TF seems legit nice) so he's floundering: "He..! ugh, he...he totally has a crush on you..."
LOL same here!...that was also one of my many thought waves because Dojin saw the way Tofu face was looking at Hyesung and got jealous!
How funny that is what i thought too cause the only one who can recognize an alpha is being an alpha and that friend of hyesung knows that dojin is an alpha right? Beta doesn't have an ability to differentiate an alpha from an omega that much as based on first chapter since they're just an ordinary beta. （￣へ￣）
I bet that's what he found out and wants to tell him
