Youngmin + Donghyun of AB6IX.
Also recognized as DongPaca, one of the cutest ships in Kpop. They have know each other for more than 6 years and MXM duo sticks together every time people saw them. Youngmin once propose Donghyun on one of the MXM's vlive and they were also asked to kiss.
YoungDong should really get married.
I love YoungDong's interactions.
My OTP.
