Click, Volume 6

Joonha is a normal, healthy boy of sixteen who has cruised through life without too many problems. Imagine his surprise when a recent trip to the bathroom suddenly reveals that he's not normal at all! With a shriek of "Oh, my God!", he finds himself missing, well, something he never thought he could live without. The truth is... his family is abnormal in the weirdest possible way: After puberty, their chromosomes undergo some kind of mutation, which converts their bodies into the opposite sex! Now Joonha has to leave behind 16 years of life as a man and live as a woman!
