MJ & JinJin

5777 votes received

MJ (Kim Myungjun) and JinJin (Park Jinwoo) are the two oldest members of ASTRO and have formalized their bond through their official sub-unit, ZOONIZINI. They debuted as a duo with the mini album 'DICE' and their lead single 'Some Things Never Change.' The title perfectly encapsulates what fans have always loved about this pairing: a friendship that has remained constant through nearly a decade of idol life. MJ and JinJin's ship name 'MyungJin' (or ZOONIZINI as the official unit name) is rooted in a dynamic fans describe as endlessly playful and warm. They are known as the goofiest members of ASTRO, prone to making each other and their fandom (AROHA) laugh, and their natural chemistry was one of the first things that drew fans to the group. JinJin has spoken publicly about how having MJ beside him made their unit album feel like a celebration of everything their long friendship represents.
