MyGO has been re-femaleized in the second playthrough!

My name is Chihaya Aine. I just returned from England and suddenly had memories from my first playthrough.
Is this the world of the second playthrough?
Moreover, the other members of the original band seem to be somewhat different as well?
It's okay, I'll still be in a band for life in my second playthrough!
...But why do they seem to be even more feminine after forming a band?
"I...I have no interest in that kind of thing!"
Su Shi: "It's okay if we have it, right?"
Takamatsu Akari: "Aine... I like it..."
Li Xi: "Take responsibility for yourself!"
Renai: "Enjoy it to the fullest—'Spring Shadows' (Deeply Meaningful)"
