You are a boy, you were walking on the street. In a kind of hallway. you saw a coin on the road, you kneeled down and tried to grab the coin.

Suddenly someone grabbed your hand, you already saw that his hand was under the blood.. he layed a knife on your hand

"Help me, or you'll be the murder. Your fingerprints are on the knife now."

(Skip time) he gave your his house location, you tried to carry him home. But your not that strong.. when you were at his house you bandaged his wound.
