AKB boasts all the members are everyone's sweethearts, and then they are prohibited to have a relationship with any man. Some people say the regulation does not refer to having a relationship but having a sexual intercourse with any male.
Anyway, the member showed apology by shaving her hair.
In Japan, workers are required to live up to as much demand of customers as possible. In the process to accomplish it, workers are forced to overwork without salary or die because of overworking. In this case, AKB members are forbidden to make love with any man. This regulation was set in order to live up to expectation of those who believe "AKB's virginity must be kept forever". This ideal requirement is hard for the members to obey, when we consider that most of them are in the age that is suitable for reproduction.
What I want to say is idols' tentative character must be separated from their real lives.
