Spoiler alert!!!!
In fact they are both scared, really in the novel it took a lot of time for them to admit their feelings face to face and because of the fear that the other person could leave, they dod not have the courage to really confess and change the things ( well they were still lovey-dovey before their confession) Guys really be prepared because really they are so lovey dovey, showing off their love ahahahahaha
Its funny how there is a high turn over of maids in the castle because they got married after seeing how lovey-dovey the duke and the duchess is hahahahhaha and that " the master's bedroom is cold even during summer" because he is always at the duchess bedroom ahhahaha
THEN WHY NOT RENEW THE MARRIAGE CONTRACT OR SOMETHING! ANYTHING YOU FOOOOOOLS
