Can Someone Please Explain What's Going On?! Volume 7

What started as a loveless contract marriage between a prestigious duke and the impoverished daughter of an earl grew into true love before they knew it. Now that Viola and Cercis have renewed their vows—and meant it, this time!—a new chapter begins in their life together. But as it turns out, they aren’t the only ones responsible for all that love in the air! While Cercis was on his quest to win over his wife, his longtime, long-suffering friend and partner-in-crime, Corydalis, was busy falling head over heels for a certain maid from the Fisalis manor! Will we see love blossom between yet another pair?
