I enjoyed this first volume enough that after finishing I instantly ordered the sequel so that I can continue it soon.

This is a different twist on the standard "reincarnated into a novel as royalty/nobility" Isekai sub-trope, since the novel in question is a BL universe where almost all the male characters end up in relationships with each other and our straight female lead is left feeling she'll never have a chance to fall in love. It's a concept which could if done badly be a little problematic but it didn't feel that way to me at all. 

Although the cover perhaps suggests this is simply a fun romantic comedy, the story is actually more complex than that with political intrigue, intriguing family dynamics and several so far unanswered mysteries. There are a few moments where the main character annoyed me (deliberately digging herself deeper into a hole) but they weren't enough to stop me overall having a very good time.
