[Sweet pet + younger brother + cold-blooded person in front of others, little naughty dog in front of others + super sweet ending]
What you think you are interested in is actually because I have been secretly in love with you for more than ten years.
You protected me more than ten years ago, let me be your knight to protect you for the rest of your life.
Only my sister can see the little puppy. My younger brother spoils me like a little princess. It's so sweet~
The content is okay, but the names are too tacky.
