Do you think Jason would be as popular as he is now without Nana?

No. Jason has a strong singing ability and a beautiful voice. He has no personality in music, which is fatal in music. I can't create yet, my aesthetics are not good, and my popularity is average. If you don't have a toilet to push you, you are likely to mix with singers who show off their singing skills in various voice synthesizers. Singing in pop music is not that important, and there are many technical explosions. Personality style and singing quotient are decisive.
