"Eh? You have a sister? Why didn't you tell me earlier?" Lin Qiao sat on a couch in her space house and turned to say to Lin Kui with surprise.
Lin Kui sat on the other couch as he looked at her silently.
Lin Qiao immediately figured it out. "Oh, alright!" she said, "You didn't trust me, did you? Or, did you worry that I might find your sister and use her to threaten you? I understand! You didn't know me well after all. It's reasonable for you to be vigilant against me."
Lin Kui did stay vigilant against her. He was grateful to her because she saved him from Huaxia Base. But in spite of that, he could not trust her completely.
He had a family, and that was his secret. He didn't dare tell anyone about her, because he didn't want to bring her into trouble.
She was his sister, three years older than him.
