Helllo this is my debut post!
Imo:
Bts: minimal change. Add cities for concerts.
BlackPink: career detour, other 3 members will get solo gigs and cfs. Slow down US promos and maybe even start releasing chinese versions of songs.
Twice: no change.
Seventeen: put as much effort as they put in Japan
Bigbang, ikon, winner: huge career boost esp bigbang could promote exclusively there.
What do you think? What about other groups?
