I think there's a bit of misunderstanding :')
Reynald, Koslov, Irene, Dimitri, and Marcus are all the protagonist of their own story. As I said, Irene, Dimitri, and Marcus will have romance/a love interest while Koslov has that possibility.
I humbly apologize for not stating it in the page (I'll fix it soon), yet I need to remind that this isn't a dating sim :'
