He's not playing them, can you please use your brain while reading a story, the plot is very simple too, don't need to be that smart to realize that Jooin is just minding his own business while these two stupid shits are harassing him at school and at home. Also, he doesn't need to chose one of them because right now you can see that he doesn't want to be with either of them.

JOOIN CAN MOTHERF****** GO SOLO...LIKE LEAVE MY MEN ALREADY...YOU ARE PLAYING THEM REAL GOOD
