I just read a article about a former idol Tina about how female idols deal with their monthly periods, and it's really awful.
“There was one day where we had to go to practice, but I had such bad period cramps. I remember asking the company, ‘Is it okay if I rest a little bit?’ And they would be like, ‘Do you think other K-Pop idols would rest?’”
''Tina admitted that she was once forced to wear white outfits by the company when she was on her period. This made her feel extremely scared, worried that something would happen. Although Tina suggested wearing dark colors, the company did not care or have any support. During the rehearsal and performance, Tina constantly asked her members to make sure that she hadn’t leaked.''
''Her group members also felt uncomfortable during their period because their teachers and managers were all men.''
''Many female idols even do not get their period for months or be late developers due to extreme dieting or having immense stress. ''
This is terrible We really don't know what happens behind the scenes
