Twin brothers and sisters like to go to school dressed as the opposite sex. The eldest lady from a noble family unexpectedly fell in love with a very handsome sister dressed in men's clothes. My brother thought that the aloof senior sister he liked was a flower on the high mountain and was not close to men, but it turned out that she liked girls. The bully in the school who the teacher has no way to deal with is actually an older brother, a neighbor and a fanboy who is very obedient.
It's a cute and silly little story about everyday life.
