Me & the ghost in my room side eyeing this asf. Wooju my baby, you dumb asshol- anyways.
I'm starting to think the main antagonist is Mr Cha, and he planned all this so Mustard would look bad infront of Wooju and that keep him to himself. I know Mustard is possessive asf but he couldn't bear to see Wooju getting hurt or even hurt him. Even the past incident must've got something to do with Mr Cha.
Just my theory with the stuff going on so far, but let's see.
