A Stepmother's Marchen Vol. 5 (manga)

It is almost the marchioness Shuri von Neuschwanstein’s nineteenth birthday, and love is in the air…for everyone else, at least! Jeremy is preparing for his upcoming marriage to Ohera, which will make him the new head of the Neuschwanstein family. Elias is off with a new girl seemingly every other day. Even little Rachel has a budding romance of her own with a foreign prince. But Shuri mustn’t let her guard down, because ever since Cardinal Richelieu voiced his suspicions about Shuri’s reincarnation, he’s been plotting. The Church isn’t yet done with the Neuschwanstein family, but instead of targeting Shuri or Jeremy, this time they’ve set their sights on someone much more vulnerable.
