The story centers around Leon, a teenager who's going through relationship issues with someone very special. Leon receives a text from that person asking for space, and possibly ending things. It's up to the player to decide what happens to the relationship - will it end, get fixed, or become something even bigger (whether that's good or bad).
Talk to people, text your friends (or don't), and try to live your life the way you see fit as you go through the relationship problems.
