This is a game about a normal human being, you, that somehow managed to enter this overly sweet sugar world. So sweet it makes you sick, literally!
You got taken in by a sweet girl named Sucrose, and she's been taking care of you the last 3 years. Although you're not getting better. The so called "after effects" of the world affects your body a lot, and in Sucrose's words it's because your body is not used to this amount of sugar in the air. She promised to keep you alive, and so you have been able to survive by her help.
Today is a special day! That is because your other friend's from this world are coming over for a tea party, meaning that you get to finally talk to them after 2 years. You want to catch up with them, and maybe along the way you'll find out what's really wrong? As you do that though, make sure your brain doesn't rot to a sugary mess.
