The husband knew he was sterile and wanted his wife to sleep with someone else to cover up that fact, how is thag "honorable"? He exploited Seok's feelings for his wife because he knew he wouldnt reveal the truth due to that.
The husband and the man were real ones, both of them are honourable and do what it takes to make the woman they love happy regardless of the situation. Love how none of the men shame the woman despite it being an unfair moment. The woman is a good woman for not letting it cloud her judgement and duties of a wife.
