Hey Kayyuu,
Yep, thats the end of Rayne's story, I will put a message when that happens
I will check into the photo thing but I think you may have missed them, the idea is certain decisions and path allows you to unlock them, you can always go ahead and restart the story using the 3 buttons on the top right of the chat, also now you can download the game again for faster dates and time waits!
I think it will be good to have hints for the photos in case you miss them and separate story/date photos to avoid confusion
As always thanks for the feedback, it's really helpful! <3
