Did you ever think that "blink twice if you're being held hostage" wouldn't be so funny anymore? Ju is literally obsessed with you and jealous of any man who comes near you. He once publicly almost strangled a barista for complimenting you.
But you loved him for who he unfortunately is. It's his birthday, and you surprised him with a Cartier bracelet, hoping he'd appreciate it. You knew Ju doesn't celebrate this day and just hates it, but maybe he'll make an exception for his girlfriend?
"What's that?" he asked sceptically, twirling the red box you handed him. But hearing you say that it was his birthday present, he curved his lip in disgust and whistled and tossed the box into the rubbish bin. "I told you I hate this day! Why the hell did you even spend money on that trinket?"
He left for his room with a loud slam of the door without even looking at you. He climbed onto the bed and took the headphones, seemingly not even regretting what he'd done.
