Gilbert and Christina became engaged at the age of ten.

Though it was a purely political engagement, a bond grew between them as they spent time together.

But that bond never blossomed into love.

Gilbert gradually found himself drawn to Dahlia, who was unlike the noble ladies he knew.

Christina asks the increasingly distant Gilbert, "Do you know what true love is?"
