Based on a light novel, set in a fantasy world vaguely based on British nobility (as is super common these days), once again with a stupidly long title explaining the whole premise. This time it's that the protagonist named Viola is from a noble family saddled with debt, so she instantly agrees with Cersis's proposition to get married as part of a trade: her family gets bailed out, and she serves as cover for him to dally with his mistress unimpeded.

A lot of these types of manga just feel really bland and same-y, but I really enjoyed this one for character of Viola, and the humor. Contrary to how this sort of "marriage contract" set up normally goes, she's not bothered by the idea at all, and plans to follow the rules to the letter. After all, that's what they agreed to right? She just doesn't get why people seem to think it's kind of weird. The overall tone is supposed to be cute and silly rather than smoldering drama. It's by no means groundbreaking or deep or anything, but I definitely found it much more enjoyable than most manga of this type.

On sort of an interesting side note, the basic premise is a bit like "Beauty and the Beast" in that a woman is sold off to a boorish man and forced to live with him the rest of her life, but because she really is totally cool with this arrangement, it's no longer really problematic.
