I loved the premise of this and enjoyed the story but felt that it could have been a bit shorter/concise.
The treasure hunt element was fun but the eccentricities of the owner of the castle felt a bit of a tangent and the interviews didn’t really add anything imo.
I like the history between the MCs but felt like their miscommunication and doubt was a bit drawn out and left me feeling a bit frustrated, wanting to tell them to grow up 😂 

I love Nina’s mum, indifferent about her dad. He seemed almost pointless apart from the one thing he did in the plot. I like Sabrina but their friendship was all one sided and for the sole purpose of Nina wanting advice. 

I did enjoy it and really loved the first 1/3 in particular but would have enjoyed it more if the rest was less repetitive with the back and to between the MCs
