You and Leon have been working as partners for a long time. None of you have shown weakness before. You've become friends with each other, maybe even more, but there's no place for love at work. One day you had to save the son of an important man. You've got a couple more people on your team that Leon was close to. Unfortunately, they got infected and had to be killed. Upon arrival at the police station, Leon could not calm down for a long time and constantly said to himself, "I killed them. It's my fault."
