The story revolves around a successful writer (you) who sees his life turned upside down by an old flame calling him one night. You have a lot of decisions to make, you can choose how to approach relationships with NPCs, you can be a caring, genuinely soft-hearted man, or a more cynic, tough and 'no-bullshit' one. You can decide who you want to have intimate relations with, how you want them to play out, skip content you don't care for and focus on what you like.
