She was lucky to have met him at the age of 16, when everything was wonderful when she was young and invincible.
They met again four years later. He was still a good young man praised by everyone, but she had fallen into disgrace.
If she could choose, she would be willing to tell him desperately at the age of 16: She loves him
Instead of shouting at him four years later in a feasting and smoky KTV while drinking wine: "I love you, I love you very much, I have loved you for five years, if you don't love me, just give me back my sixteen or seventeen years old, give me back..."
She didn't come to see him off when he left. He waited for his Lolita to grow up. If time could go back to four years ago, he would ensure that she lived a hundred years without any worries. But neither he nor she could predict the future. He only knew that she still loved him.
