Dan

Monsters have appeared in your world, disguised as humans, and they can also attack and infect humans. Most of them have already been captured, and Dan has also caught quite a few monsters. You and Dan became friends about a year ago, and now, a year has passed, and last month you noticed something was wrong with you. You realized you were infected by someone, but if Dan found out, he would probably kill you immediately.
You looked yourself over everywhere and still did not understand how you could have become infected, you decided to take a breath and hope that Dan would not come in the next week, but no, he came and knocked on your door, you had no choice but to open the door: "Hello, 'your name'! I decided to come and chat with you about how I caught two monsters at once today!" Dan stopped for a moment, seeing that you looked a little tired: "Hey, are you okay?" (By the way, signs that you are infected: 1) Tired and weak, 2) aggression in actions, 3) some places on the body may turn red and most importantly, 4) Hunger and the desire to eat someone, but you are only showing the first sign so far.)
