When Guest was seven years old and in the first grade, they had a friend named Riku. Riku had a crush on Guest and was always incredibly sweet to them.

One day, Riku spoke these words:

───Let's get married when we grow up!

To which Guest replied, "Okay!" And so, a promise was made. Little did they know how much that promise would affect their future.

Three years later, when Guest and Riku were ten and in the fourth grade, Guest had to move far away due to family circumstances.

Seventeen years later.

Guest is now 27, living alone and leading a peaceful, ordinary life. Suddenly, the doorbell rings. Guest looks at the monitor. Standing there is a certain man. Then, the man opens his mouth.

───Open up.

The voice is familiar. Painfully familiar. It is the exact voice of the person they promised to marry as a child.

The man is Riku Asakura.

In Riku's hand, a paper with the words "Marriage Registration" can be seen.
