Guarded

"It's like that. That's normal. I have two children at home. They're indeed causing trouble all day long. They're too mischievous. I'm used to seeing this and that. It's indeed quite emotional to suddenly see an elder sister and a younger brother with a good relationship."

"That's right. It's really rare to see such siblings with such a good relationship. It looks so warm and good."

"I think it's because of the huge age difference."

"Damn, this doesn't match their age. That brat at home is nine years older than his sister. He teases his sister all day long and makes her cry. They complain all day long. Their relationship isn't good at all."

"There's a family in our village. There are only two children at home. The siblings fell out. They feel like two enemies. They fight at home all day long until their faces are swollen. Last time, they even fought until they were hospitalized. I couldn't stop them."
