Even though she had heard the rumors from the internet, after reading the actual script, Ye Shuang understood why this character was so hard to master. After the elder brother died, the main character practically used every living moment of his life to pay tribute to his brother.
He placed his brother on a pedestal and kept repeating their memories together in his mind. To not forget those memories, to not forget that person, the main character turned over a new leaf because he knew that was what his brother would have wanted him to do. Therefore, he kept improving himself, striving for the top. Even though it would not bring his brother back, but he wanted to do something for the man.
It did not matter whether the real brother was that perfect or not. After all, the script did not have that prequel… but in the main character's heart, his big brother was the epitome of everything great and good.
