Well, without having read the 'Romantic Killer Novel', it's hard to say for sure. However, if we assume the basic premise of the title, there would likely be a main character who is the 'romantic killer'. This character might be someone who has had a bad experience with romance in the past and now wants to prevent others from experiencing it. Then there would be the other characters who are on the receiving end of the 'killing'. They could be a diverse group, including people from different backgrounds and personalities, all with their own ideas about love and relationships. And there may be some characters who are in between, not fully on the side of the 'killer' or the lovers, but rather trying to find a balance in this chaotic situation created by the 'romantic killer'.
