i'm sad that you can't see minh as darcy at all :(
he fits perfectly to me, as svmgie said in the 2kr he got more honest with his love in the last period of time, and he used to be really reluctant with showing tenderness and affection. one of the most prideful people whose heart got stolen by a cute boy.
he's really reserved and closed with most people, even cold at times, but tender and loyal with those who love, as himself said. it just takes time for him to open up. i would argue he's one of the most darcy-coded people ever! i can see his sarcasm and confidence as elizabeth too, but darcy comes first in my mind for him, i hope you can see the vison!
