I don't remember! When I found out about it, I liked it!
When I went to karaoke when I was really young, I came to know it when the adults were singing LOVE Machine.
Morning Musume-san。 was super popular!!!
After I became an Egg.
I found out about it when I saw ℃-ute-san's Hagiwara Mai-san on Kirarin☆Revolution.
I came to know the group Morning Musume。 after seeing Takahashi Ai-san's performance, so from there. (if I remember correctly)
My big sister
I found out about it when my mother and father showed me videos from the time called Morning Musume。-san's Platinum Era.
Though I knew about it well before, I came to like it after S/mileage-san's song "Choto Mate Kudasai!"
After seeing S/mileage-san's indies single MVs, I learned about Hello! Project after searching info about them.
Until then I didn't know that Morning Musume。-san was part of Hello Pro.
