The family is falling apart, parents quarreling when they meet, feeling like air at home, and having no friends outside except studying.
This lasted until his seventeenth birthday. His parents had a quarrel when they met, and he had long been accustomed to it.
When he was sleeping, "Happy Birthday to You" came out of his headphones, bringing him into a dream.
In the dream, he had an older brother. His parents had a harmonious relationship, and his family was rich. Everyone doted on him. He had good social skills at school and had many friends.
After all, it was a dream, and he still had to wake up. After being awakened by the homeroom teacher's phone ring, he escaped from the dream.
Back to reality.
At night he was transported back to the dreamland, and he understood that he could go back as long as he slept.
He began to prefer sleeping and not going to school.
His mother died of alcoholism, and the only person he cared about in the world died.
He wants to stay in a dream forever
Intention: Since reality is not good, let's go to the dream
