Great Men Academy is about a girl who turns into a boy, but can turn back into a girl at night and returns to a boy in the day. Another boy does fall in love with her, not knowing she is actually a girl. They do share one kiss at the end while she is in her male body.
Ceki you can be the judge on if it goes on the list or not by the description, or should we somehow do a vote for Great Men Academy (if so, I think only those who watched it should be allowed to vote)?
