Song Qinghuan looked up, puzzled at him, "Why?"
Shi Yuhuan paused, then said, "Grandpa...no, he's not my grandpa."
"Not your grandpa? What does that mean?" Song Qinghuan questioned, puzzled.
Shi Yuhuan hadn't told Song Qinghuan about Shi Xiuren yet, so she didn't know the grandfather wasn't a true grandfather.
Previously, it wasn't that Shi Yuhuan didn't want to tell Song Qinghuan, he just didn't know how to explain it to her.
Now that it had come up, Shi Yuhuan intended to tell her everything, "I have thoroughly investigated. My actual grandfather died forty years ago, before I was born. He was killed by the man who now pretends to be my grandfather, who has undergone plastic surgery to resemble him. My parents, your brother, their misfortunes were all due to him."
Song Qinghuan opened her mouth in shock, "Not a real grandfather but a man who has undergone surgery to look like him! God, this ... going on for 40 years and no one has realised, it's really terrifying."
