Translation of more of the Fanaccount by @Henecia-momo on weibo
Taken from the comments section
She was talking to her friend, saying that HJ hadn't been to Jaksal for a very long time, and both were watching the Jaksal staff and thinking of HJ when suddenly someone appeared beside them, wearing a cap down low so they could only see the lower half of his face. They were thinking yet another handsome guy had appeared, but as they looked, they realised something wasn't right... It seemed like HJ.. And looked some more... It really was HJ!
She got her passport and passport cover signed while her friend had her passport and phone cover signed. She'd actually wanted to get an autograph on a photo but had left it at the hotel and had nothing for him to autograph on, since they hadn't expected to meet him there.
At the time apart from her friend and herself, there was only one other table with what looked like Japanese fans seated there.
He had his head down playing on his phone, humming softly but they couldn't hear what song it was he was humming.
He seemed ok, looked his usual self.
