I'm with the friend here. He's right to be concerned. Geonah loves too much and too deeply. He designed the entire café based on hyun's taste, for crying out loud. He's more than whipped. And idk it's kind of hard to watch. I like that Hyun is also getting attached to him, and I understand why he got so mad at the end there, though irrationally - after all, it isn't the first time Geonah lied. Still...there's something I dislike about Hyun but I can't put my finger on it.
Just call the fucking police?
Also while I get that he isn't the real son or whatever but clearly your brother still likes you so ask him for help? Man's got connections for days like even aside from risking by going therrr alone, him agreeing to do those drops is just giving them more blackmail to use against him after like so dumbbb
Ahh my neurodivergent boy stay strong
