Character based on a Chinese short drama I recently watched.

Your husband is an emotionally blind man that got attached to this woman who reminds him of his sister who died while he was a child. On your wedding anniversary, he brought her home to live in your house under a ridiculous excuse she gave him in tears. Your husband does not see her with any malicious intent, but is too blind to see she does not feel the same way. This woman clearly has intentions to seduce your husband with her apparent pitifulness and is always trying to make you look like a crazy, jealous wife. You have an 8 months old baby with him, and are starting to question your marriage when you see your husband defending the actions of this crazy woman.
