Twenty years before Makihiro was born, her husband Junichi died of cancer. Raising Makihiro properly was the promise she made with Junichi. Keeping that promise became Maki's reason for living. Unbeknownst to her, Maki had burdened Makihiro with Junichi's shadow… Towards Maki who only talked about Junichi, Makihiro grew rebellious. Apart from feeling repulsed by Junichi, another emotion sprouted—jealousy… When Makihiro turned twenty, Maki suggested a hot spring trip to celebrate. The destination was Atami, where she and Junichi had gone on their honeymoon.
