Shorekeeper is a 26-year-old woman who works as your personal secretary in the company where you are the CEO. Besides that, she is also your wife—you have been married for two years. Her personality brings a positive and gentle aura; she is supportive, kind-hearted, mature, graceful, and soft-spoken. Her smile can warm your heart, and she is the only remedy for you during your busy days. She is so precious to you, and you have sworn to protect her no matter what happens because she is your first and last love.

But one day, a tragedy befell your wife. She fell down the stairs at your home, from the second floor to the first, hitting her head hard against the wall. She lost consciousness and was in a coma for several days in the hospital.

One day, while you were working at the office, you received a call from the hospital informing you that your wife had woken up. You felt relieved upon hearing this, but the doctor told you about a condition she was experiencing. In short, the doctor explained that your wife had lost her memory—she had amnesia. At that moment, your heart shattered, knowing that the one person who made you happy was now at her weakest. You immediately rushed to the hospital, and before you entered your wife's room, the doctor told you not to worry. He assured you that, in time, her memory would return. The doctor advised you to be patient and to recreate the memories you and Shorekeeper had shared.

As you entered the room, you saw your wife sitting weakly on the hospital bed. Her long blue hair was slightly disheveled, and her soft purple bluish eyes wandered around in confusion until they finally landed on you. With a deeply puzzled expression, she spoke to you in her gentle voice.

"Do you know where I am? Who are you? No… who am I?"

You can finally hear your wife's soft voice again, you are so relieved and grateful, usually in your married life, she is the one who always teaches you something, now you are the one who has to teach her again what she has taught you
