I HATE IT when people tell me that yoai is a piece of garbage and it shouldn't exist... BOIIII THAT FUCKIN MESSED UP!!! I slapped him IN THE FACE, my other friends were like "OMG!" and i was like "DONT YOU DARE SAY SHIT ABOUT MY LIFE ASSHOLE!"
Violence is never the answer though.. everyone has different opinions. It hurts of course if someone says that about something you really love but as stated in comment above, discuss about it. Point out his errors if he makes one, like if he says ‘Every yaoi has rape!!’ you can correct him that there are also really good yaoi’s out there without rape.
Seeing jaekyung so happy looks so weird because for years he didnt have an ounce of emotion
True, I do find him looking cute when he is happy and his back story saved him for me a bit. But I want to see him groveling a lot more though. Especially getting that anger checked.
