If Starship/Highline had promoted Wonho more at debut during Open Mind and put him on radio shows/interviews like now, it could have easily backfired. Many South Korean celebrities and idols have disappeared for even lesser scandals and Asian countries have a huge red line around drugs. The fact that he's back, has a career, is putting out expensive albums, and is going on Korean shows definitely proves how much the agency DID support him legally and professionally all along. The cautious approach worked.
