Gu Yiyi was actually repeating these two words subconsciously in a rhetorical tone.
However, Wu qingyin treated it as if she was calling him.
"AI," he replied seriously.
When she answered with this word, Wu qingyin's heart changed and a strange feeling filled her heart.
He found it a little strange, but he did not reject this feeling. Could this be the feeling of kinship? it was different from father and son, but more like real siblings. It was a kind of affection similar to that of people of the same age.
It felt good to have a younger sister in this world, especially when she thought about the things she had experienced. Wu qingyin suddenly had a feeling.
That was, he should become better and stronger so that he could protect his sister!
Although her mother had explained a lot of things to Gu Yiyi in the letter, the reluctance and worry in her words were genuine.
His mother loved him, and she loved Gu Yiyi too.
