The Echo of Falling Pen

This is a story about "wrong choices". A genius chooses to use mathematical precision to hurt the person he loves most, and a girl chooses to use seven years of hatred to cover up the love that has never disappeared. He thought this was the best ending - she would go to England with a bright future, and he would be alone in pain recalling the girl who once rested on his paralyzed legs to bask in the sun. Concept: The ultimate sacrificial male protagonist × the growth-oriented female protagonist
