"Psychological shadow? What's that?" Susu asked, puzzled.
"It means he has had some bad experiences, which affect his attitude towards people and the way he handles things," Yuze explained.
He wasn't sure if Susu could understand, but he tried his best to explain.
"What kind of bad experiences has the big nephew had?" Susu inquired.
"When my older brother was little, he was also quite reserved and didn't like talking, so he didn't have many friends. According to my dad, when my brother was seven, he went to a summer camp, and somehow, he got bullied by the other students. They stripped him naked and made him run hundreds of meters," Yuze recounted.
"Stripped him naked? Which bastard stripped the big nephew naked? I'll beat them up!"
"Don't rush, don't rush, that was many years ago," Yuze quickly stopped Susu, explaining, "At that time my brother was only seven years old, that was over twenty years ago."
"Oh. I see," Susu nodded.
