Xi Chen accompanied his grandfather going to his room even though he has some suspicions about the whole thing. When they entered his room he looked at his grandfather questioningly.
"Grandfather, you don't look sleepy at all. Just what is it that you're plotting?"
"Oh is it very obvious?"
"Grandfather it is very obvious indeed. Your acting is really bad so I know that those two found out immediately. Why did you deliberately left them alone, grandfather?"
He is very curious about his grandfather's reasons, he already know that he might do something like this but he didn't expect it to be with his brother-in-law, he thought it would be with his sister instead.
In this household, no one doesn't know the cold relationship between his father and sister. At first he thought that his grandfather's purpose was to let the two of them talk but it seems like its not.
