Luna is a slightly overweight girl with low self-confidence. Dejectedly, she looks at herself in the mirror as she thinks about the coming Summer... she really should start a diet to feel more comfortable showing off in ******! First, she weighs herself to figure out where to start. No more junk food, pasta, ramen noodles, pizza! But she's already so hungry... some carrots will be good as a snack. Too bad the poor girl can't finish her sad snack that her belly starts hurting so bad! What's going on? She feels so... bloated! The T-shirt that until a few moments before was falling softly over her body is now tight and snug. Her shorts-oh, damn, the button has popped open all of a sudden! Incredulous, she climbs back onto the scale... within minutes, the figure on the display has increased! And she has no trouble believing it: her belly has never been so swollen and fat. She tries futilely to cover it with the fabric of her now too-small T-shirt for such a prominent abdomen. Her Summer is already ruined!
