That won’t work on Yujin, though. Yujin has a lot of fear that kept him from wanting to even admit his own feelings for Aaron. He wouldn’t even admit that Aaron had any feelings for him either. He’s been traumatized thoroughly by his father to feel safe anywhere, too. That’s why he ran away and has been in hiding in the first place. Although, Aaron’s current method is still no-go, the communication may not fix the situation easily when Yujin wants to avoid the truth. It may take a lot to get Yujin to properly face his own and Aaron’s feelings without him suddenly wanting to retreat to his usual indifferent attitude and hiding behind mocking Aaron.

Aaron: “how can I get him back and keep him from wanting to run away?”
Us: “talk to him and tell him how you feel. Communicate.”
Aaron: *proceeds to trap and assault*
