Okay so for the ones that are confused the guy with the red hair got a pill from his friend that make like you know "horny" and he put into jiwoon drink and thats why he was on the floor when suha found him. He passed out because it was too much.. So basically the dude with the red hair drugged jiwoon with a sex drug
Girl I love you... I totally forgot this existed until you updated back to back thank you bro
