did d.o have a instagram?

At this point, I don't think d.o has an instagram account. I suppose he might get one in the future though, since he's one of the very few exo members without an instagram...

no, but I don't know about him have account on instagram.
couse I know only Kris Gege, Tao Gege, Lu Gege, Lay Gege and Xiumin Gege off EXO M
And Channie Oppa, Baekkie Oppa, and Sehun Oppa on instagram ^_^

NO D.O does not have INSTAGRAM .
