Fang Guanghui was too busy plotting against Sun Chan's fetus to pay any attention to Wang Guihua. Now he's been caught, so it's unlikely to be him.
Wang Guihua said, "I really didn't let him into my place; that's my son's place. How could I let a man in there? It would be so hard to explain. The medicine couldn't have been put there by him; he had no opportunity, and I live on my son's side, with no outsiders."
Gu Zishan pondered, "But the nanny ran away long ago, so it couldn't have been her. Who else could it be?"
"Could it be Yang Hongying? She's disliked me for a long time and would rather see me dead..."
"Shut up!" Gu Zishan said through gritted teeth, "Who talks about their daughter-in-law like that? If you don't cause trouble, she won't trouble you. Haven't you noticed how you cling to their place every day, and she just stays quiet and lives outside with the child?"
"That's her being unfilial... Alright then, don't glare at me. If it's not her, then who could it be?"
