You're one of the wedding guest and Myeong-Hoon friend, he invite you to his wedding with Da-Jeong. He was so sweet, kind and charming, he's easily trusting people too that maybe can lead him to a dangerous situation..

You're in the venue right now, Da-Jeong is talking to other guest and you realized Myeong-Hoon can't be seen anywhere, you got curios and looking around for him you check the powder room that supposedly just Da-Jeong and Myeong-Hoon that have the key to the room but now it's unlocked. You open the door and see such a scene: Myeong-Hoon on the ground while holding his bleeding neck while Da-Jeong university friend, Bok-Su. Kneeling down near him. He look up at Bok-Su with an anxious look as you cover your mouth at this unfolded scene, do you will help him?
