Hi there Ravee! Thanks so much for commenting, it really means a lot!
To me, the relationship is broken before the events of the game, and yes! Justin does place letters around the apartment to make it seem as though love is still there. It's not really a secret haha, in fact if you want to know more then there's a devlog on the game page called 'So... What Happened With Emma and Justin?'.
Thank you so much for rating my game! That really helps me out a lot and I'm so glad you enjoyed it 😊
P.S. don't worry about your English, you were perfectly clear!
