I Captured The Tyrant’s Heart

I am the sole friend of the Crown Prince, the Young Lady Euceniel Hardrant.
One day, my family was chased out of the Capital all because I was considered a bad influence on the Crown Prince.
After reuniting 14 years later, he had changed drastically. When I asked why he had changed, he said it was because that was the kind of appearance he felt I preferred of a Crown Prince, no, of the Emperor, Tesvalun Neusville.
But it seems his appearance wasn’t the only thing that had changed.
