At the age of twenty, she came to this time and space that had never appeared in history in order to complete her doctorate mission. In this inexplicable time and space, she met him who was persecuted, had a withdrawn and extreme personality. It has become her habit to take him in and love him. At this time, he was just an eleven-year-old brother to her, but in his heart, she had become his only constant pursuit.
When I came back here again, it was already nine years later in this time and space. At the age of twenty, she found him, who was also twenty years old. At this time, he has become a cold, cruel, "big devil" who is feared by the world... The only thing that has not changed is that he still pursues her persistently.
She came to this time and space against the Doctor's wishes for the last time just to join hands with him. And can he still wait to get the only happiness in his life this time?
Parting is also a new beginning!
