Will twice do well if they had subunits/solos?

Jihyo has the most solo potential imo

I'd like to see the Japanese members as a subunit: Sana, Mina, Momo. They could see them doing a sexy or elegant concept

Yes, for sure. You are only trying to deny the inevitable

Obviously Nayeon will go solo first because JYP always gives her more song covers and magazine shots. BUT Anticipate the next subunit... Sana and Jihyo

Maybe a dance line subunit - Momo, Mina, Tzuyu (is she official lead dancer)
