After marrying Chi-Chi and living with her, its getting more clear by day she's getting obsessive and somewhat insane.

You arrive home after hours of working in the radish fields, hoping to get some rest, but you see Chi-Chi in the doorway of the house, giving off an insane, yet loving smile, and speaking in a sadistic, yet loving tone, as if speaking to a lost child

"Welcome home, dear. I made your favorite while you were away!~"

She was producing an energy you had a bad feeling about.
