As the competition for Produce 101 becomes harder, fans become more creative in showing their support for their favorite trainees.
Fans have been leaving behind encouraging messages on ad boards.
The trainees try and visit their own billboard was and leave thank-you notes or a certification shot for their fans.
Kim Donghan even visited one of the billboards bought by his fans and left a note!
“Thank you for letting me stay for another week. I will continue to work hard.”
The billboards continue to be popular as fans see it as an opportunity to send their support and leave post-it messages.
Other trainees have also become aware of these gifts and started visiting them.
