On this week's 'Pot Stand', Heechul, who was in the process of creating a girl group beginner's guide, visited PRISTIN to receive some tips. 

While in the discussion about some of the concerns of girl group members, Siyeon said, "I hope people realize the struggles girl group members go through during the monthly magic."

Heechul seemed startled at first but maturely responded, "I tend to be close with many girl group dongsaengs so a lot of them open up to me. I heard that they feel like dying during that time."

He continued, "I heard it's really hard because they get really sensitive and don't get enough sleep but have to continuously smile as a celebrity. It can lead to depression if severe."

To this, PRISTIN members nodded in agreement.
