I agree with what Jul3-san said.
When I heard a news about her, I searching about her... I saw Annin in her face.
I'm totally happy about her statement.
She's still young but she already had a big heart to show who is she and she isn't ashamed of it.
We often (always) see members clinging and kissing and hugging with each other, but this is the first for me to hear the confession like that. Brave! Good move!
She's cute.. and I hope she's a good dancer and singer too.
So people didn't assume that she said the 'bisexual' statement just for get the attention from public.
Mayu... you better watch out. She'll try to kiss you too later.
