Five years later, Kotoko Aihara came back.
With her son Yano Kazuhiko,
Wearing a diamond ring,
Back.
Dounan Hospital, Kotoko Aihara and Naoki Irie meet again
Qinzi actually became an anesthesiologist?
Naoki graduated from Tokyo University?
What have they experienced in these five years?
What will happen to them in five years?
Why, my fiancé Yano Ryuichi is here too?
Intention: trust
