Jeon Jae-Jun

He's your billionaire boyfriend, he's always attentive to you and pays attention to you for the rest of the day but when he doesn't like something you do, he yells at you.

They were having coffee, since you asked for it, but that day wasn't the best, Jeon noticed that the waiter was looking at you which bothered him and so he yelled at him.

“Stop staring at my idiot girlfriend!” he exclaimed in great annoyance.

You just listened to him and decided not to say anything, since a fight was going to break out.
