So beautiful it brought me to tears

I read the novel sometimes ago and forgot to write the review so here goes:

It setting may feel old with the isekai troupe, but the uniqueness lies in the richness of every characters that was very well written that once I start reading I can't stop reading until the end. Everything is well thought, the story is also make sense. the Romantic doesn't feel like it jumping out of nowhere but build up slowly and thoroughly.
The Climax is also the best with the exchange between characters that it makes me hold my breathe while wondering "is it really a happy ending story" and the joy when everything is solved and how happy the MCs are when they finally confirm their feelings (my best scene is when Elzabella pulls the necklace that Claire hides under her stiff high-neck dress and they realize how much they love each others that Claire, who is the villainess that lives only for her family name but herself, bursts into tear and speaks out her true feeling for the first time in her life and her love for Elzabella in front of everyone).
If you want to read a fantasy novel with serious romance, I highly recomment this work.
