Yes, for now Vanya only has one scene in the game, more are planned, but she will get them in the future when I completely revamp her model, erotic scenes, house, and everything else, because it is the first model in the game and maybe my second animation ever, it is in poor condition and needs to be revamped, though not right now, because it will make more sense to do it when my skills improve a lot more.
Additionally, after obtaining Vanya's underwear, you can take a closer look at it at the player's house, where you will find a guide to this system. Unfortunately, I forgot to add this information in the game in this update.
