After delays, SS501's Park Jung Min finally released his first solo effort, "Not Alone" last month. For this release, he has held various promotions and recently he held a fan signing event in Synnara. At the event, Park Jung Min received a scare when a fan wore a scary mask and ran to the signing table. Park Jung Min's reaction to this was priceless and he jokingly refused to sign the autograph for her. Luckily for us, the whole thing was captured via fan cam, check out the hilarious clip below!
