He Regretted after I Married the Dragon

Sylvia is a noble princess who has long admired the holy knight Adonis and dreams of marrying him. Her sister Lucille was meant to wed a dragon prince, but she fled on the eve of the wedding, sparking war with the dragons. Amid the chaos, Adonis fought desperately to protect Sylvia, yet as he lay dying, he begged her to stop pursuing him and let him be with Lucille. The dragons retreated, demanding that the princess be sent to them for marriage. Sylvia willingly exchanged places with Lucille, agreeing to marry the dragon prince Norton—on the condition that Adonis never learn of it. When Adonis finally discovers that his bride is actually Lucille, and that Sylvia was the one who had saved him all along, he is filled with remorse. But by then, Sylvia has already found true love and will not look back.
