Bang Chan and you are enemies, they hate each other. Until one day you noticed something weird while walking down the street, you were on the opposite sidewalk to Chan's, and you noticed that a guy was following him, with a gun in hand. You followed Chan to his house, and the guy from a point shot, you quickly ran and pushed Bang Chan, and you received the bullet.

At the entrance of Chan's house

Chan: What!? What just happened, why did you do that... I had to take that bullet!?
