I think maybe I am able to provide some information about it!
The first drama (the pre-order one) is about a radio show hosted by Geordo, Keith, Alan, and Nicol, and the guests are Rozy and Silva. They receive letters from the audience and give solutions to their questions. They also report the news that happened in Sorcier. But during their talk, no matter which topic they start to talk about, the conversation will always surround Catarina eventually. At the end of the show, Mary calls in the show and declares that she has stolen Catarina and that she is going to take her to Quid. Being shocked, the four hosts rush towards the place Mary and Catarina at and leave the two guests on the show. So the show is canceled and no longer to play due to the mess.
The second drama is about the six male characters who are vampires in this story. Geordo and Alan are the royalty of the West kingdom, Nicol is the noble of the West kingdom, and Keith is the adopted son of the human noble family. On the other hand, Rozy and Silva are the royals of the East kingdom. (By the way, Catarina is human, and she is not Geordo's fiancée in this story.) The story begins with the feast of Geordo and Alan's birthday, which is going to be held recently. Since the vampire royal family in the West kingdom needs to choose human or half-blood for a spouse, Geordo wants to announce the marriage with Catarina in the feast. Keith strongly disagrees. While they are arguing with it, they hear that Catarina is bite by the royalty of the East kingdom (Rozy bites her), and she even disappears. Thus, they rush to the hotel Rozy and Silva are and ask them if they or the radical of their country hijack her. Then they find that Catarina doesn't disappear. She goes out just to get some spring water and make tomato juice. She even escapes from danger since the radicals like her tomato juice and let her go. But she can't join the feast because she is hurt on the way home, and it is dangerous to have the blood smell on her since it can attract other vampires. Silva thinks that a feast without Catarina is boring, so he plans to steal her away quietly...
The third drama, which is also the last one, is the story about Catarina visiting the Ristorante Villainess in order to send an umbrella to Keith due to the heavy rain outside it. All the guys are the staff of the Ristorante, and Rozy is the owner of it. Since Catarina goes all the way to there, her clothes are wet, and Rozy asks Alan to prepare some hot drinks for her to warm up. Catarina chooses milk tea for drinks. Throughout the time waiting for the drink, Nicol and Geordo talk to Catarina, and Geordo wants to do something to her but being stopped by Keith. Alan brings her the drink and some sweets. After that, the boys have some daily conversations, and Catarina finishes the food quickly. However, Catarina's face is somehow red, and others find that she has a fever. They take her to the lounge and decide to take care of her in turns. So everyone starts to take care of her in turns and tell her their feelings about her. When it comes to Silva's turn, Catarina has recovered. Therefore, they take her to the door and find that there are already some customers waiting. So everyone stands at the door to welcome the customers.
This is all I remember. I am not sure whether I have misunderstood. So, if you find any mistakes, please correct me immediately.
