I'm so glad you're enjoying it!! So about romance, it's not exactly that there's "romance" and "non-romance" options, it's more like first you need to build a friendship or at least positive relationship with them by being more intimate. Later you'll have the option to pursue a certain love interest fully after Belphie is back from the attic, like essentially a separate "route" for each love interest. The options to to get closer romantically will be pretty obvious so don't worry about struggling :)
