Thanks for asking, in terms of scenes the plan is to have the same number of scenes overall for straight and gay paths, though the balance of scenes per chapter may vary depending on how if fits the story(ex. in chapter 5 there may be 6 gay scenes and 5 straight, or vice versa).
When it comes to main Lis per side, there are 5 per side planned. There are also characters who may get scenes but not a full romance (there's no romantic ending planned for these character).
