It looks like Luhan met up with Zion.T recently!
The former EXO member uploaded a photo of a signed item (is that a frisbee?) from Zion.T on his Instagram, thanking the singer. Zion.T wrote alongside his signature, "It was nice meeting you. Next time, let's greet each other more brightly."
Luhan must be a fan of Zion.T's music!
