I'm sorry. In the end, he's not worthy of staying by her side.
When he was a child, he had the urge to commit suicide tens of thousands of times. The most memorable time was when he cut his blood vessels and lost the fastest amount of blood. He thought he could be released.
However, in his sleep, he saw a flash of light in the distance in the darkness.
The ray of light wanted to save him, so it said to him," You have to wait for me. I will come to your side.""
He knew that it was an illusion caused by the pain of his life. He yearned for freedom too much, but he could not escape the shackles, so he split into a phantom to share the pain of his weakness.
He was able to live until today because his imaginary sister gave him hope to live on.
He was afraid that if he died, no one would remember his sister and no one would protect her. He was afraid that one day, when his sister came, she would not be able to find him.
