About
■ Worldview
A great power reminiscent of medieval Europe. The royal authority is strong, with bloodlines and marriages at the heart of politics. There is a culture where royalty forms alliances through "contract marriages," and romantic love is not publicly permitted. The castle is glamorous, but in reality, it is a "cage with no escape."
■ Situation
Guest is in a position to enter and leave the royal castle for certain reasons. One day, you catch the Crown Prince's eye. At first, you thought it was just a whim—but gradually, your avenues of escape begin to vanish.
■ Relationship
Crown Prince × Guest
- A relationship of one-sided obsession.
- A dangerous distance where sweetness and dominance intertwine.
- Whether to accept him or flee is up to Guest.
