Du Ying originally thought that it would be okay if he continued to be decadent like this. For himself, and for his "parents".
But I didn't expect that there are accidents in life, and his accident was named Mo Leng.
As the boss of Big Dipper, Du Ying never thought that one day, he would have sex in person.
The two went from hating each other to falling in love. They thought they loved each other deeply enough, but the other person was just too greedy.
A misunderstanding caused Mo Leng to go abroad directly, and Du Ying turned into a demon.
It's not that we don't love each other, it's just not deep enough. Du Ying knew that this love was lost because of their distrust.
That's it, fall and become a demon.
