This is one of the example sentences from 悲しい:
桃ちゃんが悲しい気持ちの時は、お父さんもお母さんも辛い気持ちになってしまうのよ。
When you feel sad, Momo, neither your dad nor myself are happy.
What part of the sentence is causing the negation? (Not happy)
I’m guessing it’s something in になってしまう but I don’t really understand.

I definitely read it as 幸. Thanks for pointing that out!
