THIS! I fully agreee with your review, bittersweet and sad ending NEEDS a good explanation, a good bridging for it to be satisfactory, which clearly does not exist in 2521's ending. It feels forced and unnatural after the whole development that they built for the first 13 episodes.
I love her in Be Melodramatic and fall in love with her even more in Vincenzo, she can pull off two very different and opposite character, such a talented actress, and of course she's very beautiful ❤️❤️
