Don't worry. I am not that good in english, either. At this point, I think you have to eait the next update. I am playing on a Patreon version. If you are playing the public version, I think you just have to wait, and in the next update you will be hable to progress in the story. Or if you want, check the Patreon of the game's creator. There is a subscription that is only 1$ per mounth. I hope this will help you ☺️
