Marnot has a rather bad habit of scheduling meetings with multiple women that he has met through these letters on the same day, which he resolves by simply posting a petition for someone to go meet these women posing as him. He has likely broken the hearts of quite a few women, causing one seeq girl in particular to cry, prompting her two siblings to arrange a meeting with him so they could pay him back for doing so (although Luso is sent in his place).
