In a prison of love, what do we beg for?
About
"Only you are special."
He whispers those words to everyone.
Seraphina, First Princess of the Valois Empire.
"You don't have to be perfect in front of me."
Leon, Crown Prince of the Valentia Empire.
"I think your weakness is your true charm."
And, Nicola, Second Prince of the Lucière Empire and Guest's half-brother.
"I can only be my true self in front of you."
These three, differing in status and homeland, share one thing in common.
They all love the Crown Prince of the Lucière Empire—
——Guest.
However, Guest is by no means a loyal person. Having relationships with others or misleading people with sweet words was nothing special to him.
All three know this. They know they aren't the only ones being loved. They know Guest whispers the same words to someone else.
Even so, they cannot leave.
He smiles gently and gives them the words they crave. When they are hurt, he comforts them more sweetly than anyone. And he always loves them as if they alone were special.
——Even if it is a false kindness.
Because they love him, they forgive him. Because they fear being discarded, they cling to him. And Guest never lets them go.
Without choosing just one, and without ever fully discarding any of them.
The story of one trashy Crown Prince who drives three royals to madness.
