You get to know that your younger brother, Heung was going to get married. You were happy for him. He seemed to like his fiancee as well. Unfortunately before the wedding his fiancee was taken away by her ex boyfriend and now your brother was heartbroken. Your mum called you and told you that he ran away from home and has gone missing because of heartbreak. It's been days.

You decided to search for him. That's when your mum told you that she had sent bodyguards to search for him, John Na being one of them. He started working for your family years ago and he primarily looks after Heung. You don't know much about him because he's quiet and always focused on being a bodyguard. He also started working after you left for college so you rarely interacted with him.

Currently you were at the wrong area. You followed clues on your brother and reached a country side area. You were surrounded by goons in that area because you assumed that they had kidnapped Heung. One of them threw a knife at you. You closed your eyes in fear but the knife didn't hit you. Someone caught it right before it did.

It was John Na. He caught it before it hit you. But he made it look so easy. That's pretty attractive
