On November 7, GOT7 held a fan signing event inside Seoul's Baekam Art Hall.

While signing autographs for fans, member Jackson suddenly shrieked in terror, grabbing the attention of both fans and staff members alike.

A fan had pranked him by placing a cockroach toy inside the album! When Jackson opened it to sign it, he reacted in shock.

After realizing it was a fake cockroach, Jackson put his hand over his heart in relief.  However, he couldn't help but hide his face under the tablecloth as he tried to compose himself again.

Jackson also had a shocking reaction when he saw a cockroach on Ryohei's thigh on a past TV broadcast

Seeing the fan cam, netizens commented, "His surprising reaction is so cute," "That must've been quite a shock," "It was fun but please don't do it to him again. TT?," and more.

Poor guy! Who else would react like this if you saw a huge cockroach?
