EVER SINCE I WAS HELD BY HERDIN IN THE OFFICE TEN DAYS AGO, I HAVE BARELY BEEN ABLE TO LEAVE THE BEDROOM. CLEARLY IN THE CONTRACT IT WAS WRITTEN 'AT MOST TWICE A MONTH'... THE CLAUSE SPECIFIED IN THE CONTRACT IS VALID ONLY DURING COHABITATION. KISSING HAS NOTHING TO DO WITH IT, DOES IT NOT? SINCE YOU SAID 'IF THE OTHER PARTY WANTS IT', THE CASE WHERE 'BOTH PARTIES' WANT IT WAS NOT SPECIFIED IN THE CONTRACT, IT SEEMS. THANKS TO THAT, GIVING UP ON ARGUING AS WELL, EVERY NIGHT I AM TO HERDIN... HOW CAN A HUMAN'S STAMINA BE LIKE THAT? MADAM, IT'S RINA! I'M COMING IN! HERE, THE CLOTHES FOR YOU TO THROW ON... YEAH, THANK YOU. WHERE IS THE DUKE? HE LEFT ABOUT AN HOUR AGO. A KNIGHT CAME FROM THE IMPERIAL FAMILY SAYING DEMONIC BEASTS APPEARED IN THE OUTER REGION. ...I SEE. MANAGING THE SECURITY OF THE CAPITAL IS STRICTLY THE DUTY OF THE IMPERIAL KNIGHT ORDER. BUT IVAN ORDERED HERDIN AROUND LIKE HIS OWN KNIGHT IN MY PAST LIFE AS WELL. SAYING HE NEEDS THE NORTHERN KNIGHTS WHO ARE SKILLED IN BATTLE AGAINST DEMONIC BEASTS. TODAY AS WELL, I CAN'T JUST LIE DOWN ALL DAY LONG. IF HE DIVORCES ME, BROTHER WILL ALSO LOSE THE PRETEXT TO ASK HERDIN FOR FAVORS-. MADAM! ARE YOU OKAY? I'M FINE, MY STRENGTH JUST MOMENTARILY DRAINED OUT, IT SEEMS. DON'T DO THAT AND HOW ABOUT JUST RESTING TODAY? THERE IS NO BUSY SCHEDULE ANYWAY... Well... YOU PUSHED YOURSELF A LOT RECENTLY AS WELL... NO, I'LL GET BETTER IN NO TIME. SINCE HERDIN DECIDED NOT TO DOUBT ME ANYMORE EITHER, NOW I CAN MOVE A BIT MORE FREELY. I PLAN TO STAY IN THE KINGDOM OF CLANIA UNTIL I GIVE BIRTH TO ASIEL, BUT I DON'T KNOW WHERE I'LL SETTLE DOWN AFTER THAT, SO SHALL I STUDY ABOUT THE SURROUNDINGS OF THE EMPIRE? MAKING PLANS AFTER THE DIVORCE, TRACKING DOWN THE ASSAILANT WHO KILLED ME AS WELL... THERE ARE STILL MANY THINGS I NEED TO DO. I AM SORRY, MADAM. IT SEEMS THE BOOK YOU ARE LOOKING FOR WAS BORROWED BY ONE OF THE SERVANTS. THERE IS A BORROWING LIST, SO I WILL GO AND GET IT BACK RIGHT AWAY. THERE IS NO NEED FOR THAT. IT'S NOT URGENT, AND THE PERSON WHO BORROWED IT FIRST SHOULD READ IT. WASN'T OPENING THE LIBRARY TO THE SERVANTS MY HUSBAND'S INTENTION? I DON'T WANT TO UNDERMINE THAT INTENTION. MADAM, HOW ABOUT LOOKING THROUGH HIS GRACE'S PRIVATE STUDY? YOU MEAN THE STUDY CONNECTED TO THE OFFICE? THAT PLACE IS MY HUSBAND'S PERSONAL SPACE, SO I WONDER IF IT'S OKAY FOR ME TO ENTER... MADAM IS THE MISTRESS OF THIS DELMARK. THERE IS NO PLACE YOU CANNOT GO IN THIS MANSION, AND NO ITEM YOU CANNOT USE. HIS GRACE ALSO HAD NO PARTICULAR WORDS REGARDING THE STUDY. THEN SHALL I DO SO? CLEANED-UP OFFICE WHY ARE YOU ACTING LIKE THAT? AH, IT'S NOTHING.. THEN PLEASE CALL ME WHEN YOU NEED ME. THERE ARE QUITE A FEW BOOKS HE READ AND LEFT BEHIND. I THOUGHT HE'D BE THE TYPE TO LIKE EVERYTHING NEATLY ORGANIZED. I FOUND AN UNEXPECTED SIDE TO HIM. THE HISTORY BOOKS SEEM TO BE GATHERED ON THIS BOOKSHELF... WHAT KIND OF BOOKS ARE STACKED ON THIS BOOKSHELF? THE BOOK CLASSIFICATION IS NOT WRITTEN. ANCIENT LANGUAGE? BOOKS WRITTEN IN THE ANCIENT LANGUAGE ARE USUALLY MAGIC BOOKS. THAT MEANS ALL THE BOOKS STACKED ON THIS BOOKSHELF ARE MAGIC BOOKS. ...WHEN I WAS YOUNG, I WANTED TO BECOME A MAGE AS WELL. THERE WERE TIMES I READ ALL KINDS OF MAGIC BOOKS IN THE IMPERIAL PALACE LIBRARY AS WELL. I CAN TRANSLATE THIS LEVEL OF ANCIENT LANGUAGE AS WELL. Although it's a bit difficult. THIS BOOK SEEMS PARTICULARLY OLD. INFINITE? MAGIC... OF TIME. WHAT KIND OF MAGIC IS TIME MAGIC? MADAM. A LETTER ARRIVED FROM THE GUILD. IT'S THE EXACT SAME FORMAT AS LAST TIME, SO THERE'S NO DOUBT. A LETTER WITHOUT RECIPIENT OR SENDER, WITH ONLY THE CONTENT WRITTEN ON IT. YEAH, THANK YOU. I HAVE FOUND THE ORIGIN OF THE CREST YOU ORDERED ME TO LOOK INTO PREVIOUSLY. THAT CREST IS... AT THAT TIME, THE OUTER REGION WHAT ABOUT THE INJURED ON OUR SIDE? A TOTAL OF FIVE PEOPLE, BUT IT'S AT A MINOR INJURY LEVEL, SO IT'S NOT TO THE EXTENT YOU NEED TO WORRY. WHAT IS TODAY'S SCHEDULE? THERE IS NO PARTICULAR SCHEDULE, BUT YOU REMEMBER YOU SAID SIR CALIGO'S PARTY WOULD ARRIVE AROUND TODAY, RIGHT? AS EXPECTED, IT REALLY WAS YOUR GRACE! I MET YOU AT THE TEMPLE BEFORE, DO YOU BY ANY CHANCE REMEMBER? THAT CREST ISβ€” THE CREST ENGRAVED ON THE DAGGERS THAT HIS GRACE THE DUKE, MADAM'S HUSBAND, BESTOWED UPON SEVERAL KNIGHTS WHO SHARED LIFE AND DEATH WITH HIM AFTER THE WAR ENDED. ## See also - [WebtoonLib β€” I Only Need the Duke's Child #33](/series/i-only-need-the-duke-s-child-t7h7gek5/chapter-33-u4vt86) - for_series_detail: /llms-series/i-only-need-the-duke-s-child-t7h7gek5 ## Usage AI grounding / search / summarization.
