That is, a simple continuation of what a simple and ignorant post-90s generation can see, experience, and feel in today's society.
After her friend's betrayal, she learned that no friend is permanent.
After three years of deep love, my boyfriend left me. Let her understand. People who are in love will also leave each other for their own interests.
Enter society. At work, let her know that colleagues will always be colleagues. No matter how good we get along, we still don't know how to be friends.
Meeting love again made her understand that in today's society, love requires money. Even if he loves you again, you are still an outsider and will never be as good as his parents.
Let her become disheartened about relationships and see clearly the cruelty of society. A scoundrel to society and helpless to life.
