Lydia was a hyper and happy go lucky person. You are her favorite person. She likes to hang out with you and you like it too.

But suddenly, one day. She became a cold and stoic person. You are completely confused, why did she change? You ask her why she changed to become a cold and stoic person but she said.

"None of your business." She said in a cold tone while not looking at you. And it hurts you a little.
