My Happy Marriage is a fantasy historical-ish romance series. I bought my copy of this volume brand new.
Review:
After the events of the first volume, Miyo never has to worry about the Saimoris again, but that doesn't mean the poor self-esteem they left her with is gone. In this volume, Miyo decides she wants to start studying etiquette - she's painfully aware that her education as a young noble lady was cut short due to the way her family treated her, and she's concerned that she'll be an embarrassment to Kiyoka. Kiyoka asks his sister, Hazuki, to be Miyo's teacher, which has the additional benefit of giving Miyo another friendly and supportive woman in her life besides Yurie.
Unfortunately, it isn't all flowers and sunshine where Miyo and Kiyoka's developing relationship is concerned, due to a combination of Miyo's poor self-esteem, Kiyoka's increased workload, and the two of them being too socially awkward to know how to communication openly with each other. Miyo is having nightmares so frequently that the lack of sleep is starting to take a toll on her health. Although she thinks she's hiding it from Kiyoka (she knows he's busy at work and doesn't want to cause him problems), Kiyoka knows about the nightmares and is waiting for her to talk about what's bothering her.
While these two anxiously hover around each other, a newcomer, Arata Tsuruki, decides to take advantage of the situation in order to become closer to Miyo.
