I'm a thief?

-"Why I am a thief?" - Koutarou, in 7 years old, asks himself. - "I'm just a boy that takes what I need, right? This makes me a thief? Thiefs are the bad guys that we see in TV... I'm not a bad kid, am I?"
Koutarou stare at the ceiling.
-"My mom and my dad would think that I'm a bad boy...?"
Silence.
-"I have no way of knowing about this..."
Silence.
-"Who were my parents?"
Of course, nobody answered this question.

The base is mine.
