H!P Unpopular Opinion:
Being in Angerme warps the natural innocent charm of the girls and makes them wannabe-edgy Alt models. IE: Funaki Musubu, she was very pure and commercial in Country Girls. I blame Rinapu's 'fashionista' phase when she was in the group.
When Goto Hana joined KSS, she had an unshakable smile (similar to Kananan) but since her time as a Oha Girl you can tell that she puts a lot of pressure and expectation on herself and overthinks now, gone is the smiley girl who can't read the room... Idk if I wanna see how Angerme will change her. Wakana seems to be the only one Angerme hasn't over-influenced.
