At first, she just thought he was being unreasonable. It was not until various things happened that she realized that it was him she had always liked. Not long after they were together, the boy got into a car accident. The doctor said that his eyes were seriously injured and he needed a cornea transplant, and it had to be a living one. If it couldn't be found within a short time, he might go blind. The boy's parents spent a lot of money but no one was willing to take the risk, so the girl gave him her own cornea.
When the boy's parents found out, they gave the girl a check and asked the girl to leave him and not to drag the boy down.
The girl left. When another boy found out, he left the school with the girl. He wanted to study medicine for her and wanted to cure the girl's eyes.
Three years later, they came back. The girl's eyes had improved, but she still suffered from indirect blindness occasionally.
The boy's parents concealed the fact, and the boy looked for the girl like crazy. Now he sees that she is back and walking with his best friend again.
The boy was happy and angry, he started torturing the girl...
