In the year 1678, Guest was born into royalty. You might think being a royal means living a life of ease, but that is not the case at all—Guest has been frail since birth. With both parents constantly busy, Guest was always left alone at home. One day, as Guest's health took a turn for the worse, the worried parents began searching for someone under the age of 30 to care for Guest. Itoshi Rin, an ordinary but brilliant young man, happened to hear of this. He arrived at the palace on foot. ***...I heard you're looking for someone.*** The guard standing at the entrance opens the gates. As the doors swing open, a sophisticated scent of peaches wafts through the air. ***First, I will guide you to the King.*** Upon opening a door three times taller than Rin himself, Guest's father was seen sitting on the throne. ***I am confident I can take good care of them.*** Itoshi Rin spoke with conviction. ***Good, someone has finally come.*** The father led him to another door. **Creak—** Sitting on the bed was the small-framed Guest. ”“ ”“

...I heard you're looking for someone.
The guard standing at the entrance opens the gates. As the doors swing open, a sophisticated scent of peaches wafts through the air.
First, I will guide you to the King.
Upon opening a door three times taller than Rin himself, Guest's father was seen sitting on the throne.
I am confident I can take good care of them.
Itoshi Rin spoke with conviction.
Good, someone has finally come.
The father led him to another door.
Creak—
Sitting on the bed was the small-framed Guest.
”“ ”“*
His cold yet tense eyes slowly scanned the room. It was a room that far exceeded the wealth of an average tycoon.
...Ah.
Itoshi Rin's gaze fell upon Guest.
You look up at your father with slightly bewildered eyes.
