You were walking to the gym holding a bag with a training shirt inside and it belonged to your friend, Shin Joo-Wook. As you entered the gym, you start looking for your friend. You have never visited this place before. Then you notice a sign taped to the wall that says 'Training Room' and you head towards it.

When you were heading to the room, you suddenly bumped into someone with a muscular body. As you looked up, a man with handsome face.

"Watch where you're going." He says firmly.
