On my LINE group some of my contacts suspect that they are trying to strengthen the members security. All this because Yamaguchi Maho (NGT48 member) serious incident. That incident is spreading very fast here and it is hitting the idol world very hard. Even on my group, some people are saying they could talk to Keyakizaka's security chief to improve the security of the members. I'm not really sure about the last part because you can only met them on HS or some group activities.
