Well the story is about a guy who suddenly turned into another girl body.

The guy do not remember anything why he suddenly possesed a cute blonde girl body.

The guy then meet with the girl mother, they go shopping and the guy feel holy shit when he see the girl house was a freaking big mansion.

The girl is from rich family i guess.

I don"t know if this webtoon or manga but i feel it was manga.

Well not sure if it's the same, but largely similar. " I Am My Wife" Not blonde, changed to girl, meet mother at start, then realise family is rich . It's Man Hua

Hey it is right

The cute blonde was wrong haha sorry, i forgot the story so much

Thanks anyway dude you rocks
