Love and Sin

I'm a single father. Lately, my son has changed.

Always so mild-mannered, he's suddenly become irritable and quick to anger.

Today, on the way to school, he said he saw a classmate kill someone.

I wanted to take him to the police.

But then I found a bloodstained fruit knife in his schoolbag.

Just then, the police called to say he was suspected of murder.

I'm sure someone is trying to frame him.

He's everything to me. I have to catch the real killer and clear his name!
