The Melancholy of the Duke's Son

Since letting Graythia, a woman of rare bloodline and education, slip away, the search for a suitable empress for Prince Lexus had reached a dead end. Eugreace, the duke's son who serves as his close aide, refuses to offer up his sister, so he approaches young ladies and clan heads with proposals, but they go nowhere. Having learned a portion of truths he was previously unaware of, Eugreace finally realizes his own foolishness. ※This is from the perspective of Eugreace in the "That's Why I Lie at the End" Graythia series.
