Thanks for playing! Lexan and Duran are the only two who are romanceable for the MC, and you can see their sprites on the page.
I'm kind of disappointed. Usually, an otome game has at least three pursuable characters...two is just ...
Though Nova can be categorized as an otome game, romance and pursuing a relationship isn't its main focus--the focus is mainly on the plot and character development. It's not like there's a complete absence of romance from it, so I hope you will still try out the full game and see if you like it! Our team has been working hard to deliver a great visual novel and would love for you to enjoy the story/world of Nova.
We should learn to be content and appreciate every creator's games. They take a lot of time and hard work in their hands to finish. We should be thankful rather than ask for too much-- not when the full game hasn't even been released yet. Just saying.
