When will RESCENE be able to secure as many international fans as LE SSERAFIM?

‌Seeing the success of LE SSERAFIM's North American concert this time, if they can build an international fandom as large as theirs,
I feel like Minami will finally be able to have the successful international tour she truly wants....
How long will it take? Do you think a RESCENE solo international tour will be possible within about 2 years?
