The only group that had success was 365daband and it was because of pure luck. None of their successors has gained anywhere near them.
With the latest news of LIME disbanding and the more than fewer than handful groups left, I think it’s time for vietnamese agencies that are planning to make their own idol groups, to rethink and maybe change their ideas.
I don’t have the answers to why VPOP groups keeps failing. Culture, economy, too much KPOP influence from groups and the people may be some of the reasons. But clearly the formula that many attempted after 365 does not work and I doubt it will ever work.
I propose this: Agencies can have a idol trainee program, but not for debuting in domestic groups, but rather send them to Korea. China is doing this by having trainees trained in China and afterwards sent to Korea for more extensive training. With all the korean investment and partnership in vietnamese entertainment industry, why can’t this be done? It’s clearly vietnamese becoming idols in Kpop will have more goodwill from vietnamese audience than trying to make a Vpop group doing Kpop. LIME was that attempt, but failed.
