The story is basically about a bullied overweight guy that turns into a hot girl with some hugely sized chest equipment. It's not super innovative or anything, but it's reasonably interesting as that particular kind of a wish fulfillment type of show. S/he has a series of troubles like buying underwear and various job related stuff. She tries and somewhat manages to get back at some bullies too and then gets involved in some pretty serious mystery. It has a number of ecchi scenes and some interesting side characters, like a girl that helps him out with shopping and stuff from the very beginning when he'sall surprised and confused.
