This is just an essay. I know the word count is very small. I don't know if anyone will read it.
This story is a serious drama~
There are two parts to the story.
Part 1
Falling out of love before you start falling in love
Part 2
Love like boiling a frog in warm water
Character introduction:
Dudu: blood type A

PS: There is a plot where a dog turns into a human, but it is not a surprise. But if you see something and you don't like it, just shoot it, that's okay.
