[Long Story: Published as a Book] I Only Casually Handed Over a Handkerchief at a Evening Party, Yet a Knight is Pressing Me Into an Engagement

At a ball for finding a fiancée that she reluctantly attended, a noble knight received a handkerchief for a chance encounter that she handed to him "casually"—and the next day, he shows up in her territory demanding a proposal. ...A story of a knight who has developed an unrequited obsession and desperately pushes his once-in-a-lifetime chance, and a countess's daughter who is unfamiliar with romance. ※This is the short story version.
