As someone who (co-)wrote stories in the past this game resonated deeply with me. It's been 15 years since I've written anything about them or made any progress to their stories and I will likely never touch them again, yet the characters still follow me (even if some of them are very vague now like that rose story you had) in my heart obviously but also sometimes on games such as Tomodachi Life. To me, your game felt like a love letter to all kinds of story writers out there who really care about their "babies".
May I also add that your art is breathtaking, the way you draw hair is so beautiful especially! And that starry world...!
One last thing, was [MC] able to keep her promise? Anyway, thank you for making this game!
