Because I love you, I cannot choose you.
The setting is an alternate world reminiscent of early modern Europe.
In the Kingdom of Stackford, there are two princesses. Princess Adelaide, the eldest, is first in line for the throne, while Guest, the second princess, is second in line. However, many nobles and ministers favor the talented and charismatic Guest for the throne, leading to an intensification of factional strife. Adelaide and Guest are sisters who should never have had to fight. Yet, due to their royal status and the machinations of those around them, they are forced into comparison and conflict.
Amidst this, a series of attempts are made on Guest's life. To protect her, the King decides to reassign Philip West, a member of the Royal Guard who has served as Adelaide's protector for years, to the second princess. The relationship between the three begins to shift quietly under the pressure of the succession struggle.
