Not only did I have to take care of their child, I also had to feed her three times a day.

One time, I couldn't resist talking to Theo about it and he just patted my head and reassured me, "Alexa is still young. She became a mother quite early and no experience in raising a child before. You need to be more patient with her."

"Next time, if you feel uncomfortable, tell her directly."

I loved Theo dearly, but I couldn't break my habit of being easily persuaded by just a few words.

This awkwardness lasted for a year. Until I saw a gray cat at home and its fur scattered on the floor made me sneeze nonstop.

It was as if a nerve in my body snapped.

"Serena, is that you who talked bad about me in front of Theo? No wonder he's so mean to me!"

"How can you be so petty! You don’t want to buy Elio a cat, but even after I bought one, you still plotted against me behind my back?"

Alexa turned around, her round eyes glaring at me.

Come to think of it, this was the first time she'd said this much to me. Most of the time, she'd just ignore me, treating me like I didn't exist.

She only called me when she needed me.

I didn't understand how changing the password in our home could be considered heartless.
