After Being Abandoned, My Sister Regretted It

(Sister who is cold to the outside x gentle and caring on the inside and a child who is arrogant on the outside x but longs to be loved) Winter three years ago. Shen Yu stood there in a state of disarray. He asked Shen Qingyu, "Why do you do this? Whether I am in your heart or not, it doesn't matter!" But he screamed at the top of his lungs, but got no answer, only the back of the person leaving indifferently. Shen Yu once went to find Shen Qingyu but heard that the other person only regarded him as his sister. After hearing this, Shen Yu made up his mind that he would never have any wrong thoughts about her from now on. Shen Qingyu looked at the girl in front of him. Knowing that this is not allowed. But you can't fool your own heart. After perfecting his career, he decided to come back and make up for the regrets he had at that time. But I find that the child seems to have changed, can I still get her back?
