Recently, the members of the new boy group attended the recording for KBS variety show 'Happy Together 3'. The schedule was private, meaning it was not officially announced to the fans. However, the sasaeng fans somehow found out the exact time and date of the recording and crowded outside the studio. 

At the appearance of Wanna One members, the sasaengs took out their cameras and started filming. It's reported that they also got extremely close to the members, making it impossible for them to walk by. One fan even reportedly hurt Lee Dae Hwi by accidentally pushing him with her camera. 

This is not the first time sasaeng fans have got out of hand. Several weeks ago, Park Ji Hoon, Ong Sung Woo, and other members of Wanna One were captured almost being crushed by a crowd of fans outside YMC Entertainment building. 

Many expressed concerns for the safety of Wanna One. Angered fans also criticized YMC Entertainment for the poor security and demanded they improve protection. Comments stated, "Sasaeng fans are so annoying. I'm going to go beat them up if they hurt my babies", "Look at Dae Hwi's face TT poor Dae Hwi", "They are crazy!", "What kind of agency is that? They need better security!"
