The side-story was a bit confusing. First we hear that the second mixing invites extended family, only for the actual thing to have solely the parents and one of Thorsten's brothers plus his wife present, with excuses being made for the missing siblings alone. Siblings are usually not considered extended family as far as I know. There's also a sentence that makes it sound as if engagement feystones are exchanged at the second mixing, if the mixing itself goes well, only to once again be contradicted by the actual event, when the pair only makes the decision when to exchange the stones, and even decides to exchange them unusually early, rather than waiting for the third mixing. This feels like someone in the writing or translating pipleline mixed the second and third colour mixings together.
But the final scene with Angelica trying to copy Rozemyne's mannerism was just adorable. :3
